Allen-Bradley 1734D-IA16S Analog Input Module

The Allen-Bradley 1734D-IA16S Point I/O module is a 16-channel AC input block for the POINT I/O system, designed for DIN-rail mounting in industrial control panels. It accepts 120 V AC signals on 16 inputs, enabling direct wiring of AC-powered sensors and devices to a single 1-slot module. The IA16S is designed to be mounted on a 1734-MB mounting base and wired through a removable terminal block, specifically the 1734-RTBS spring-clamp terminal block for fast, tool-free connections. This module is part of Rockwell Automation’s POINT I/O family, allowing scalable expansion of I/O networks with straightforward integration into existing Rockwell ControlLogix/CompactLogix architectures. With 16 inputs in a compact form factor, it supports efficient wiring of multiple control circuits in machine panels and remote I/O deployments while simplifying diagnostics and maintenance.
