{"product_id":"allen-bradley-1746-ig16-16-point-dc-input-module","title":"Allen-Bradley 1746-IG16 16-Point DC Input Module","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 1746-IG16 is a 16-point digital DC input module for the SLC 500 family that reads TTL-level 5 V signals from sensors and switches. This sourcing-type module accepts 5 V DC TTL inputs with an operating range of 4.5–5.5 V DC and an off-state threshold of 2.0–5.5 V DC, with each point drawing about 3.7 mA at 5 V and a backplane current of roughly 140 mA for the entire module. The 16 inputs are designed to be wired to a common in a Rockwell Automation backplane, providing a compact, high-density interface for digital devices in legacy automation systems. Typical installation literature and datasheets consistently describe 1746-IG16 as a 16-point TTL input module (5 V) that supports sourcing inputs, making it suitable for reading discrete signals from pushbuttons, limit switches, and other TTL-compatible sensors in SLC 500 racks. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658975215918,"sku":null,"price":25.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_0779f619-61e9-4c43-85eb-c8b600ae1b80.jpg?v=1769526230","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-ig16-16-point-dc-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
