Described in listings as TRNSTR (PNP) EXP UNIT, the module provides transistor-type outputs in a PNP configuration to drive field devices directly from the expansion module. The unit is powered from a 10-30 VDC sourcing supply, a common arrangement for 1745 expansion modules, enabling the added I\/O to operate from the controller’s field power while maintaining straightforward wiring. Typical applications include expanding I\/O on manufacturing lines, material handling, conveyors, and process-control tasks where SLC 150 controllers manage larger numbers of sensors and actuators. As an 1745-series expansion accessory, the 1745-E157 complements other TRNSTR-type modules and should be used with a compatible SLC 150 controller for proper operation.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658993041710,"sku":null,"price":97.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_f09b2dd2-45cb-42b6-90a1-b4a66122e33e.jpg?v=1769526359","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1745-e157-plc-module","provider":"PLG Automation ","version":"1.0","type":"link"}
