General purpose Up / Down event counter with Preset and two mains rated relay outputs (one for Up count Preset number and one for the Down count reaching zero). Count input accepts a simple make contact closure (e.g. a push button, relay, etc.).
The board is designed for use in a wide range of industrial counting and process control applications.
A separate board houses the four-digit red LED display, indicator LEDs and control buttons:
The main control board uses a microcontroller based circuit to drive all the functions and has two mains rated relay outputs:
Further count input signals are ignored when the UP or DOWN relays activate:
The current Count value, Preset number and count direction are stored in memory using a 3V backup battery pack (not included) so counting will resume where it left off on powering up.
Kit version includes solder for assembly.Specifications
