The CD6-5R/12-24V digital pulse counter is a microprocessor device with a 6-digit display. It counts up to 999999 and has one output relay. The counter is reversible and can sum and subtract pulses. It has two inputs "A" and "B", and operate together with an encoder or a sensor with two phase-shifted outputs type "NPN" (OVM1-18.24.F). Programmatically can be set various parameters defining the operation of the counter. The device has an energy-independent memory. The pulse counter is designed for installation in a dashboard (panel montage).


The CD6-5R digital pulse counter is a compact microprocessor device that serves to sum and subtract electrical impulses. It is designed to operate in combination with an encoder or a sensor with two phase-shifted outputs type "NPN". The counter visualizes only positive numbers. Except counting the impulses, its main function of the counter is to switch the electric circuit, in which it is turned on when a set value "N" is reached. The pulse counter is widely used in automation of production, technological and other processes.
