Allen-Bradley 1794-IB16D FLEX Digital DC Input Module

Description

The Allen-Bradley 1794-IB16D FLEX Digital DC Input Module is a distributed I/O component belonging to the Allen-Bradley FLEX I/O product line, designed to integrate a variety of field instruments and electrical devices into automated control systems. This module features 16 current-sinking digital input channels, supporting connection to devices such as pushbuttons, limit switches, proximity sensors, float switches, process switches, relay contacts, and contactor auxiliary contacts. It operates with an input voltage range of 19.2 to 31.2 VDC, with a nominal signal level of 24 VDC for reliable compatibility with standard industrial DC devices.

Compatible with FLEX I/O communication adapters including Ethernet, ControlNet, and Remote I/O, it also pairs with terminal bases such as 1794-TB32, 1794-TB32S, 1794-TB62DS, and 1794-TB62EXD4X15. Each input channel is equipped with an LED status indicator that activates when a signal is received, simplifying active channel identification and input device verification. Built for high-density applications, it supports hot insertion and removal for flexible system maintenance. Its rugged design includes an operating temperature range of 0 to 55 degrees Celsius, vibration resistance up to 500 G, and shock resistance of 30/50 G, making it suitable for demanding industrial environments.
