Encased in a robust, zinc die-cast housing, this module processes up to eight digital inputs from typical proximity sensors, switches, or photoelectric barriers. It integrates high-speed EtherCAT fieldbus communication via shielded M8 connectors, offering standard EN 61131-2 Type 1\/3 input characteristics with a 3.0 ms input hardware filter for excellent noise suppression. The mechanical protection and direct-to-machine mounting capability eliminate the need for traditional terminal junction boxes, significantly reducing field installation overhead and cable routing complexity.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;

The 24 V DC sensor supply distributed to Pin 1 across all 8 input channels is shared. If you are powering high-current draw devices (such as optical distance sensors or external valve indicators), keep in mind that a transient short circuit on a single channel will trip the sensor supply voltage for all 8 channels simultaneously.
