Description
A-B 1771-ACN Allen-Bradley AC Input Module for Industrial Control Systems
Let me tell you about this workhorse module we’ve been shipping for Midwest automotive plants. The 1771-ACN handles AC signal conversion in harsh environments where voltage fluctuations are common. We’ve seen it survive 5+ years continuous operation in paint shops with chemical vapors – not bad for a 90s design.

Found in legacy systems across North America’s heavy industries – steel mills love this module for monitoring furnace cooling systems. Works perfectly with 1771-BA, 1771-BS power supplies and pairs with 1771-OCD outputs. We recently helped a paper mill retrofit their digester controls using this module – let me share the full case study if you’re curious.
Guizhou Yuanmiao Automation Equipment Co., Ltd. keeps 30+ units in Shanghai warehouse for urgent needs. 12-month warranty included. For current pricing and lead times, drop me an email with your project details. Personally, I think it’s worth checking stock before ordering new – these modules often outlast their supposed EOL dates.
