Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1791-16A0 is an Allen-Bradley 1791 Block I/O AC input module that provides sixteen discrete 120 V AC input channels, grouped into two banks of eight, along with integrated status and communication indicators. This module functions as a self-contained remote I/O device - combining power supply, PLC interface, and input signal conditioning. It is commonly used in distributed control systems where modular placement near field devices (e.g., switches, proximity sensors) improves wiring efficiency and maintenance speed. The 1791-16A0 is suitable for industrial control cabinets or machine-mounted networks.
