The unit is equipped with 16 digital inputs configured in a highly dense arrangement, accessible via a standard 25-pin D-sub interface.\u003c\/p\u003e\n\n\u003cp\u003eOperating as an EtherCAT P device, this module integrates both ultra-fast EtherCAT communication and power distribution (for both system\/sensor supply Us and peripheral voltage Up) into a single, specialized cable. The inputs conform to the EN 61131-2 Type 1 and Type 3 electronic standards, ensuring broad compatibility with 2-wire and 3-wire proximity sensors, limit switches, and photoelectric sensors. Built-in Distributed Clocks functionality guarantees precise latching of input states relative to the master system time.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n
