653 Series Multi-Function Multi-Range Solid State Timer Counter

The ATC 653 is a micro-processor-based control that can function as either a timer or a counter, and as an electronic repeat cycle timer. It has a 4-1/2 digit LCD that can indicate 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, perfect for applications requiring an electronic repeat cycle timer. Additionally, there are 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 including the electronic repeat cycle timer mode. 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 the 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 by a keypad lockout command. The keypad also enables 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 Model 653, serving effectively as an electronic repeat cycle timer, is housed in a standard 15-terminal plug-in round case. Models are available for operation on either 120 VAC or 240 VAC. Counting can be done at either line voltage or at 12-48 VDC/24 VAC.
