UCNTR6A - UNIVERSAL 6 DIGIT COUNTER

 

The Universal 6 Digit Counter is a high brightness 6 digit LED display incorporating a built in up/down counter. The unit includes two relay trip outputs for upper and lower alarm outputs. RS485 Modbus communications enables many counters to be networked together back to a PLC or PC. This networking facility can be used to read the count value, or to clear/preset the count value. The alarm limits can be preset over the network or by means of digital inputs.

 

Standard features of the logic on the unit are :
Separate Up / Down Counter Inputs.

Two separate inputs allow the counter to be used as an up counter, down counter or both simultaneously.
Battery Backed-Up Counter.

In the event of a power failure, the counter and alarm preset values will be maintained.
Programmable Filter on Counter Inputs.

A filter is used to prevent false counting which may be caused by relay debounce, etc. This filter is setup using the DIP switches on the side of the unit..
Upper and Lower Alarm.

Two relays are used to give alarm outputs when the counter has counted up to a preset upper limit or counted down to zero.
Built In Power Supply.

The built in power supply enables potential free contacts to be used without the need for an extra power supply.

 

OPERATING DESCRIPTION

The counter is initially setup by programming the upper alarm limit. This is done by switching on input 3 for longer than 1 second. The first digit will begin to flash indicating that programming mode has been started. Switch 4 is now used to setup the correct value for this digit. Switch 3 is now used to advance to the next digit. Once all the digits have been setup, the value is saved into the upper limit alarm memory and the counter displays the count value. The counter can be used to count down from this value, or can be cleared by pressing switch 3 and 4 simultaneously.

Counting is performed by pulsing input 1 for counting up or input 2 for counting down. The input filter can be setup by using DIP switches 9 and 10. Refer to the DIP switch table. The count value is from 0 to 999999.

Leading zero's can be turned on by switching on DIP switch 8.
