EL1054 | EtherCAT Terminal, 4-channel digital input, NAMUR

The EL1054 digital input terminal acquires signals from NAMUR field devices according to EN 60947-5-6. The sensors are supplied with a voltage of 8.2 V and return a diagnosable current signal. In this way, a wire breakage or short-circuit can be detected in addition to the switching state. The LEDs indicate signal or any error states, channel by channel.
