Solid-State

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 Model 653 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

jumper selected.
