{"product_id":"allen-bradley-1771-igd-plc-module","title":"Allen-Bradley 1771-IGD 16-Point Digital Input Module","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 1771-IGD is a 16-point TTL digital input module designed for the PLC-5 family and 1771 I\/O backplanes. It provides 16 5-volt DC digital inputs with TTL-level signaling, using TTL current-sourcing inputs to reliably detect state from discrete sensors and switches. The module is part of the Series A 1771 I\/O lineup and is commonly paired with a 1771-WH wiring arm to simplify field wiring. Operated from a 5.0–5.3 VDC supply, the 1771-IGD draws about 130 mA from the backplane, enabling it to sit alongside other 1771 modules in a PLC-5 chassis. This 16-point input card delivers straightforward, high-density input interfacing for PLC-5 control logic, enabling quick reading of multiple digital signals from industrial sensors, switch boxes, or other discrete devices.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46244009181418,"sku":null,"price":48.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-079.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-1771-igd-plc-module","provider":"GTG Hardware","version":"1.0","type":"link"}
