It is designed to be used in a PLC-5 I\/O rack, mounting in the standard 1771 backplane and wiring via a compatible arm such as the 1771-WH for field connections. Each of the 16 discrete inputs is suited for 120V level devices like sensors, switches, and relays, enabling straightforward integration with legacy automation equipment. Electrical characteristics include a nominal input voltage of 120V with an input range typically cited as 79–138 VAC, and a per-module current envelope around 195 mA at 120V, corresponding to roughly 23 W of supply power. The module supports an operating temperature range from 0°C to 60°C, making it suitable for many industrial environments. As part of the PLC-5 ecosystem, the 1771-IAD aligns with standard PLC-5 wiring conventions and addresses within the PLC-5 discrete I\/O scheme, offering reliable, rugged performance for retrofits or expansions that require 16 high-voltage digital inputs in a legacy control system.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":46244006592746,"sku":null,"price":232.0,"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-iad-plc-5-input-module","provider":"GTG Hardware","version":"1.0","type":"link"}
