The SLN-94 counter is equipped with single counting, hold, stop, clear/start inputs. Is designed for up-down counting of pulses in 3 decades and has single program register using for programming the batcher function. SLN-94 has two build-in relay outputs (N.O.) with selectable thresholds and modes of operation. It can be used for controlling of external devices. The counter is prepared for cooperation with NPN as well as PNP type sensors, Due to internal digital denouncing filter simple contactors can be used as sensors. Additionally build-in sensor supply output (24V DC) can be used to supply contactors and some types of electronic sensors.
