Digital pulse counter for DIN-rail
Price 54.6 EUR no VAT

The CD4-2L/220V digital pulse counter for DIN-rail mounting is a microprocessor device with a 4-digit display. It counts up to 9999 and has one output relay. The counter can be started in three ways: a) by turning on the supply voltage; b) by pressing a button of the front panel of the counter; c) by using an external button or sensor connected to the counter. Programmatically can be set various parameters defining the operation of the counter. The device has an energy-independent memory.

FEATURES

The CD4-2L digital pulse counter is designed for for M35 DIN-rail mounting. It is a compact microprocessor device that serves to count electrical pulses. The number of pulses received at its input is visualized on a four-digit display. 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.
