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.
Display board sits at 90 degrees to control board, mounted on a rigid connector. The display board holds 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.
The Kit version includes solder for assembly and solder pins for board connections.
The Pre-assembled version is supplied with screw terminal blocks for all connections.Specifications
