Specification

The 1756-IA16I is a high-performance Allen-Bradley ControlLogix AC input module engineered for demanding industrial environments. This 16-channel isolated input module operates at 100/120V AC, providing galvanic isolation between each input channel to eliminate ground loops and electrical noise interference. Designed for use with ControlLogix chassis (1756-A4, A7, A10, A13, A17), it supports hot-swappable installation and is fully compatible with all ControlLogix controllers, including 1756-L6x, L7x, and L8x series. The module features individual input status indicators, software-configurable input filters, and a robust isolation rating of 2500V AC for channel-to-backplane separation. Ideal for discrete sensing in motor control centers, conveyor systems, and packaging lines, the 1756-IA16I ensures reliable signal acquisition in high-voltage AC environments. Each unit is factory-tested and shipped with a Certificate of Conformance, ensuring 100% original and new condition.
