KL2794 | 4-channel digital output terminal 24 V AC/DC, 2 A, potential-free, short-circuit-proof


The KL2794 digital output terminal is able to switch voltages up to 24 V AC/DC using advanced MOSFET transistors. The four potential-free semiconductor switches represent a substitute for relay contacts. They are short-circuit-proof and free from wear, thereby increasing the availability of the application. The output is short-circuit-proof to a limited extent. The output transistor can cope with short-term overcurrents until the fuse is triggered. The Bus Terminal contains four channels that indicate their signal state by means of light emitting diodes.
