Designed as an expansion module for the SLC‑100 family, it connects to the processor via a 1745‑C2 communication cable and shares a universal power supply with the processor and other I\/O modules. The 1745‑E101 is available in three configurations to match your I\/O needs: a Basic expansion with 10 input circuits and 6 output circuits (wiring terminals for 10 inputs); a Relay Output expansion with no inputs and 12 relay outputs; and an Analog Input expansion with 4 analog input circuits (2 set points per input) and no outputs. Operating voltage for the expansion unit is 85–132 VAC, 50\/60 Hz. These expansion units extend the SLC‑100’s reach by networking with the processor and other modules to support common industrial tasks—from digital input monitoring and digital output control to analog signal processing—making it a suitable option for scaling legacy control systems that require additional I\/O without a full system replacement.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658993795374,"sku":null,"price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_4f54213e-05f3-464a-9e3d-3c25896ceca8.jpg?v=1769526372","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1745-e101-slc-100-expansion-unit","provider":"PLG Automation ","version":"1.0","type":"link"}
