EPX1058-0022 | EtherCAT Box, 8-channel digital input, NAMUR, M12, Ex i
The EPX1058-0022 EtherCAT Box acquires signals from NAMUR field devices according to IEC 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.
By software, it is possible to select channel by channel whether a positive switching or negative switching sensor is to be connected. Thus, no changes to the PLC are required for the connection of both NAMUR break contacts or make contacts. The red error LEDs can be switched off, which allows the connection of dry contacts without signaling an error.
