Anderson-Bolds still sells and stock timers. Timers are used throughout industrial processes. Computers, PLC's and HMI's have taken the place of timers in many instances but discreet timers still have their place. ATC or Automatic Timing and Control still makes many styles of timers.
For over 80 years, process engineers and machine designers have turned to Automatic Timing & Controls first for reliable control products. These high-performance products are engineered to provide accurate and repeatable operation in all types of industrial environments. Our products play an integral part in countless industries; including food processing, plastics, packaging, water treatment and many OEM applications. The ATC product family has expanded to include 1/16 DIN timers, panel-mounted timers, electromechanical timers, counters, solid state cube and plug-in timers, photoelectric laser sensors, and time delay relays (TDR).
The ATC 365C Timer is microprocessor-based digital timer with three rotary knobs for setting and adjustment of the Preset. The Preset can be any three-digit value from .01 Sec to 999 Hrs. The Decimal and Range are switch selectable. The high-intensity blue vacuum fluorescent display is DIP switch selectable to Timeup or Timedown. Two heavy-duty 7A DPDT relays provide instantaneous, interval or delayed output control. Plug-in panel mounting allows easy replacement without the removal of field wiring.
A compact version of the 335 Timer, the ATC 355B is its exact functional duplicate, packaged in a 72mm2 DIN-Size housing, it occupies 40% less panel space and costs proportionately less. Modern production and assembly techniques have all but eliminated hand wiring, enhancing the reliability and life expectancy of the 355B.
COMPUTER TESTED RELIABILITY: The Solid-State 355B is manufactured from a series of computer-tested plug-in circuit boards and assembled virtually without hand wiring. Because it has no moving parts in its logic circuits, its life expectancy is practically unlimited. Even the load relay — the 355B’s only significant mechanical component — has a life expectancy of 100,000,000 operations (no load). As a result, the 355B achieves an overall reliability that surpasses even the high level achieved by previous Shawnee timers.
The ATC Model 655 timer is an electronic control that will retrofit most round case electromechanical timers. the control performs the same timing modes (ON-Delay or Reverse Start Delay) as electromechanical units, and it is capable of timing ranges from 1 millisecond to 199 hours, 59 minutes. On the bottom inside of the control are DIP switches which can be set, in seconds, to establish the timing mode and time range. Our unit will plug into competitive mounted cases without wiring changes in most instances. Remove the electromechanical timer, set ours, plug it into the electromechanical timer case and you’re ready to run. DIP switch setting instructions for electromechanical timers are supplied with 655 installation instructions.
Instantaneous & Delayed: A version of the 405A is available with one set of SPDT instantaneous contacts and one set of SPDT delayed contacts. The instantaneous contacts transfer as soon as the timer is powered. The delayed contacts transfer at time out. This contact arrangement can be used to replace many conventional timers.
On Delay/Interval Timing Mode Version: A version of the 405A is available with selectable On delay or Interval timing modes. This version has a set of DPDT output contacts. When in the On delay mode, the contacts transfer at time out. When in the Interval mode, the contacts transfer when power is applied and release at time out.
Universal Power: All 405A timers can be powered using 24-240 VAC or 24 VDC power, greatly simplifying ordering and inventory management of replacement units.
1/16 DIN Housing: The 48mm2 (1/16 DIN) housing is compact and is watertight when panel mounted. The 405A is mounted in an 8-pin round (octal) socket. With an optional mounting clip, the 405A can be panel mounted.
The Dial on the 405A is extra large and is easy to read. When fractional ranges are selected, decimal points are clearly indicated.
The Mode select and Range select switches are located on the side of the unit, so that when panel mounted, these switches are not accessible to the operator. This tamper proof feature prevents unauthorized or hazardous changes to the timing mode and range from being made. The 405 timers are FM approved.
The 409A has a Push Button built into its front dial. When pressed, the timer starts and provides an interval time delay. The 409A has a set of DPDT output contacts. When the Push Button is pressed with power applied, the contacts immediately transfer. After the timer has timed out, the contacts release.
Universal Power Supply: All 409A timers can be powered using 24-240 VAC or 24 VDC power, greatly simplifying ordering and inventory management of replacement units.
Noted for its circuit flexibility, the 305E also provides the highest accuracy among analog timers. Available for either ON-Delay or
OFF-Delay operation.
The 305E provides delay, interval or pulse timing function for up to 7 load circuits through two instantaneous and two delayed switches. It features a plug-in design and cycle progress indication.
HIGHEST ACCURACY: Because of its exclusive infinite engagement clutch, the 305 has a repeat accuracy of 0.2%, highest of any timer in its class.
The 422A FLIP-FLOP is available with Repeat Cycle operation. During Repeat Cycle operation the 422A cycles ON and OFF repeatedly, allowing periodic cycling of a load. Two knobs are available to individually adjust the ON-time and the OFF-time. The 422A can be ordered with either the relay being energized during the first timing period or de-energized during the first timing period.
The 422A FLIP-FLOP is also available with Single Cycle operation. With Single Cycle operation, the 422A will cycle ON and OFF one time. This is commonly referred to as “one-shot” operation. The 422A can be ordered with the relay being energized during the first timing period or de-energized during the first timing period.
There are six selectable timing ranges available for the ON-time period and 6 selectable ranges for the OFF-time period. These ranges can be ordered as either 1 and 10 SEC/MIN/HRS or 5 and 50 SEC/MIN/HRS. Having these ranges individually selectable for ON-time and OFF-time allows for a load to be energized for a brief time over a cycle that can last up to 50 hours. This is ideal for lubrication or other maintenance functions that must occur each shift or day during a plant operation.
The 422A’s 1/8 DIN housing is compact, and designed for panel mounting. The timer is mounted in an 8-pin round (octal) socket. The front of the 422A features 2 knobs. One knob is used to set the On-time and the other knob is used to set the Off-time for the timer’s cycle.
The timing range for the On-time and Off-time can be individually set. The range select switches are located on the side of the housing, so that when panel mounted, these switches are not accessible to the operator. This tamper proof feature prevents unauthorized or hazardous changes to the timing range from being made.
The output of the 422A is a DPDT mechanical relay which is rated for 10 Amps at 30 VDC and 240 VAC. The 422A can be ordered with this output being energized during the first timing period, or de-energized during the first timing period.
A single Flip-Flop Timer can be powered using 24-240 VAC or 24 VDC power, greatly simplifying ordering and inventory management of replacement units.
The 422A has individual LED indicators for ON-time and Off-time. These LED’s provide a unique and effective method of cycle progress indication. Off before timing, the LED’s blink at an ever increasing rate as the cycle progresses: once every 3 1/2 seconds during the first 10% of the cycle, twice during the second 10%, and so on until the timing cycle is complete. (In the 1, 5, 10 and 50 second ranges, the LED is Off before timing and steady On during the timing cycle).
A versatile dial-adjustable time delay relay, the ATC 328 provides a choice of ON-delay, OFF-delay or interval operation for any timing period between 50 mSec and 10 hours...all in the same timer. Based on a unique digital circuit, it features cycle progress annunciation and is suitable for the most demanding industrial service.
Designed for Industrial Service: With a load relay that is rated for 100,000,000 mechanical operations, and power supply that protects circuit components against the voltage transients that are typical of industrial plants,the 328 has a long life expectancy even in tough environments.
An economical solid-state TDR with octal plug-in base, the 339 maintains excellent repeat accuracy despite wide voltage and temperature variations. even after long periods of down-time. Two models are available. Each has six dial selected ranges from fractions of a second to as long as 10 hours. Each model has a selectable on-delay or interval timing mode.
Wide Choice of Ranges: In addition to the short ranges expected of an electronic TDR, the 339 is also available with ranges as long as 10 hours. An unusually versatile timer, the 339 has six dial-selected ranges—from 0.3 sec to 3 hours or 1 sec to 10 hours—and provides dial-adjustable timing periods between 0.075 seconds and 10 hours. A single 339 model thus accommodates the needs of a wide range of applications, allowing the user to select easily and precisely—an appropriate range to permit optimum setting accuracy. The dial face automatically displays the selected range.
All ATC timers are UL listed.
