1756-IB16 ControlLogix 16-Point DC Digital Input Module for Industrial PLC Systems

Product Overview

1756-IB16 is a ControlLogix DC digital input module used in industrial PLC systems, machine control cabinets, production line automation, and factory maintenance replacement. It collects discrete field signals and brings them into a 1756 PLC system for logic control, machine monitoring, alarm handling, and equipment interlocking.

This module is commonly used with proximity switches, limit switches, photoelectric sensors, push buttons, relay contacts, selector switches, interlocks, and machine status devices. It is suitable for control cabinets that require a practical 16-point input structure for machine operation and field signal monitoring.
