A compact version of the versatile 333 Timer, the ATC 353B 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 ATC 353B.

A compact version of the versatile 333 Timer, the ATC 355C 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 ATC 355B.

As soon as power is applied to terminals 1 & 2 of the ATC timer, the instantaneous relay is energized and changes the states of its associated contacts (8-6-7 & 9-14-10). The ATC timer then looks for terminal 15 (the clock terminal) to receive power. When terminal 15 is powered, the internal clock circuit is enabled and the timer starts to time. When the internal clock time equals the time set on the front face, the delayed relay energizes and changes the states of its associated contacts (3-4-5 & 13-11-12). The timer is reset by removing power from terminal 1 for at least 60 msec. At reset, both relays revert back to their shelf (without power) state.

Arrangement 30 & 50 Models When power is applied to terminals 1 & 2 and 15 of the timer, the instantaneous relay is energized and its contacts change state. The timer starts timing, indicated by the display. The timing bar "" blinks slowly and the digital display indicates elapse time (Time-Up & Stop) or time remaining (Time-Down & Stop). When the preset value is reached, the display stops, the timing bar blinks rapidly, the triangular timed-out symbol "" blinks, and the delayed relay latches and its contacts change state. The timer remains in this timed-out condition until reset by applying power to the Reset terminal 16 for at least 60 msec. At reset, both relays revert back to their shelf state (without power).

Note 1: The delayed relay is a magnetic latch relay and once latched it will not unlatch even if power is removed or the unit is unplugged from the housing. It will only unlatch when power is momentarily applied to the Reset terminal 16.

In the timer mode, the ATC 385A can be programmed to cover the overall span of 0.01 sec to 999 hrs in nine ranges, and can be programmed to time in Hours:Minutes and Minutes:Seconds. In the counter mode, it can cover the overall span of 1 to 99,900 counts in two ranges. The 385 can be easily programmed to start with a momentary or sustained start signal. The start signal can also be set for a voltage or no voltage starting condition.

The ATC 652 is a micro-processor-based timer with a 4 1/2 digit LCD display that can provide an indication of either preset time remaining or elapsed. There are five timing ranges covering time values from one millisecond to 199 hours 59 minutes. The unit has both an instantaneous relay output and a programmable relay output which can be programmed for any one of 14 different timing modes.

The timing range and mode are selected with an internal DIP switch. The time value is entered using the keypad on the front face. The programmed values are retained in memory and are secured in memory by a keypad lockout command. The keypad can also be used to perform secondary functions such as reset, immediate time out, time inhibit, changing the direction of the display, displaying the number of cycles run, and clearing the cycle counter.

The ATC 652 is housed in a standard 15-terminal, plug-in, round case. Models are available for operation on either 120VAC or 240VAC.

The ATC 653 is a micro-processor-based control that can function as either a timer or a counter. It has a 4 1/2 digit LCD that can provide an indication of either the time or count value remaining or elapsed. There are five timing ranges covering time values from one millisecond to 199 hours 59 minutes. There are also three count speeds to a maximum of 7500 counts per second. The unit has an instantaneous relay output and a programmable relay output which can be programmed for any one of 14 different timing modes.

The timing range, count speed and timing mode are programmed with an internal DIP switch assembly. An external switch determines whether the time inhibit or count input takes place with application or removal of voltage. The time or count value is preset by the operator using the keypad on the front face. These programmed values are retained in memory and are secured in memory by a keypad lockout command. The keypad can also be used to perform secondary functions such as reset, immediate time/count out, time/count inhibit, changing the direction of the display, displaying the number of cycles run, and clearing the cycle counter.

The ATC 653 is housed in a standard 15-terminal plug-in round case. Models are available for operation on either 120 V AC or 240 V AC. Counting can be done at either line voltage or at 12-48 V DC/24 V AC.

The ATC 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 ATC 655 installation instructions.

The ATC 765 is a powerful, compact, economical sequential control that features an extremely user friendly programming format. Microprocessor-based, it offers 100 control levels or steps, 8 programmable relay outputs, functions with count input signals or timed input with 4 timing range values from 0.01 seconds to 99 hours/59 minutes and a host of other primary and secondary keypad functions.

It step advances on the basis of time or count which can be intermixed from one control step to the next if desired. A cost-effective control, the ATC 765 is an ideal alternative to cam timers and micro PLCs for sequencing operations. Equipped with EEPROM memory, the Model 765 can store programmed information indefinitely, without battery back-up, freeing PLCs from memory storage that can be better applied for more critical data retention tasks.

Sealed for the harsh industrial environment, the ATC 765 is equally at home in the laboratory for quality control or test applications. Two models, one for 120VAC the other for 240 VAC service, are offered. Count input can be done at either line voltage or at 12-8VDC/24VAC. For additional flexibility, the Model 765 features a 4-element DIP switch to manually select count input rate (500 or 5000/minute), time/count inhibit setting (activated on application or removal of voltage), starting mode (standard or reverse) and keypad lockout (on or off). Operationally the front panel display provides indication of; step number, time or count value and output status when the unit's in the run mode; and programming information when in the program mode. The membrane keys provide input command access to generate the desired program mode sequence, as well as intervene in the run mode sequence.
