The 6ES7143-7BH00-0BB0: This is the SIMATIC ET 200clean DIQ module — 16 digital I/O points on 8x M12 connectors, each channel individually configurable as a sink input (type 3 per IEC 61131) or source output (PNP switching to P potential). Rated at 24 V DC and 0.5 A per output, with selectable input delay from 0.05 to 20 ms. What sets it apart is the IP69K housing: it withstands high-pressure, high-temperature washdown, so it belongs in food, beverage, pharmaceutical, or other hygienic zones where an IP20 module would fail after one cleaning cycle.
Each M12 socket carries two channels (double assignment). The module supports substitute value output and I&M0 through I&M4 for asset management.
