Anderson-Bolds has been involved with Automatic Timing and Controls and their timers, counters and photoelectric controls for over 40 years and have followed them on their moves from King of Prussia and Lancaster Pennslyvania to Newell West Virginia and their ownership by Marsh Bellofram.
For over 80 years, process engineers and machine designers have turned to Automatic Timing and Controls (ATC) 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).
ATC manufacturers percentage timers, electromechanical timers, cam timers, repeat cycle timers, 1/16th DIN timers, weekly timers, time delay relays, and panel mount digital timers.
As the industry standard for timers in the USA, ATC will also custom design their timers to fit unique applications. Their timers are UL, CSA and FM approved. The FM approved timers are required in combustion control for purge cycles. (See 339 and 328 timers).
The ATC timers come in all the different modes, on-delay ( delay on make ), off-delay
(delay on break ), interval, repeat cycle, flicker, flasher, percentage, recycle, single shot, and multi-mode.
Below are some defintions of timing modes:
Delay On Make (On Delay)
Has also been referred to as delay-on-operate, delay-on-pickup, and delay-on-energize. This mode of operation indicates that the timing period follows the application of operating voltage, control voltage, or the closure of an separate initiate switch. After the timing period expires, the output is energized. Delay-on-make models are available in both solid state and relay contact output.
ATC On-Dealy Timers include the 305E, 355C, 365C, 405AR, 407A, 319E, 328D, 339A200Q2X, 339A359Q2X
Delay On Break (Off Delay)
Delay-On-Break . . . as also been referred to as delay-off, delay-on-release, and delay-on-dropout. This mode of operation indicates that the output energizes first and remains energized until after the timing period which does not begin until operating voltage, control voltage, or the opening of an separate initiate switch. After the timing period expires, the output is de-energized. This mode of operation requires standby voltage during the timing period. Delay-on-Break models are available in both solid state and relay contact output.
An ATC off Delay Timer is the Series 417
TRUE Delay-On-Break . . . Has also been referred to as true delay-off, true delay-on-release, and true delay-on-dropout. This mode of operation is identical to the delay-on-break operation above, but the major difference is that this mode of operation does not require standby voltage during the timing period. True Delay-on-Break models are available only in relay contact output.
Interval (Like an Oven or fan timer)
This mode of operation indicates that the output is energized when the operating voltage is applied, or an initiate switch is closed. The timing period (interval) also begins when the output is energized. At the end of the timing period (interval) the output de-energizes, even though the operating voltage or the initiate switch is still active.
Characteristic of an interval mode is that the operating voltage must be applied longer than the interval timing period, or the initiate switch, if required by model, must be closed longer than the timing period.
The ATC 409 Series is a Push Button Interval Timer
Single Shot ... Similar to interval, but where the interval had to have the operating voltage, or the initiate switch closed longer than the timing interval, the single-shot requires only a momentary closure of an initiate switch to provide the interval mode of timing.
Repeat Cycle (Flip / Flop )
Repeat Cycle . . . Sometimes referred to as ON / OFF timers, cycling timers, or percentage timers, the repeat cycle mode of operation turns a circuit ON and OFF continuously on a repeating basis for as long as the operating voltage, or an initiate switch is applied. While the repeat cycle timer, and the ON/OFF timer are grouped together here as repeat cycle timers, there is one major difference between the two which may prove critical for your application. With any of Artisan Controls' repeat cycle timers you can vary the ON portion of the repeat cycle and not effect the overall repeat cycle time. With any of Artisan Controls' ON/OFF timers you vary the repeat cycle time when you change either the ON or the OFF timing periods. Available in repeat cycle mode are percentage timers, as well as programmable multiple output repeat cycle timers.
ATC REPEAT CYCLE timers are the 342B200F10PX and the ATC 422AR Series TDR's.
Diversified repeat cycle timers :
TBF24ADA TBF120ADA TBF24AEA TBF120AEA
TBG24ADA TBG120ADA TBG24AEA TBG120AEA
Flashers are a special kind of repeat cycle time. The only difference is the user can control the flash rate (flashes per sec etc.) only. The ON and OFF portion of the cycle are equal (50% duty cycle).
