Digital pulse counter CD6-4/220V
N=(1 - 999999), Us=220Vac, 2 outputs 4A/220V, 95x49x113mm
The CD6-4/220V digital pulse counter is a microprocessor device with a 6-digit display. It counts up to 999999 and has one output relay. Two limit values "N1" and "N2" can be set. 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. The pulse counter is designed for installation in a dashboard (panel montage).
FEATURES
The CD6-4 digital pulse counter is a compact microprocessor device that serves to count electrical pulses. The number of pulses received at its input is visualized on a six-digit display. The counter has two output relays. Two limit values of the pulses N1 and N2 can be set. When N1 is reached, Relay-1 is switched, and when N2 is reached, Relay-2 is switched. For the counter to operate correctly, N1 must be less than or equal to N2. The pulse counter is widely used in automation of production, technological and other processes.
