Allen Bradley 1734D-IB8XOB8E Combo Module

Product Introduction

The Allen-Bradley 1734D-IB8XOB8E Combo Module is a highly reliable digital input/output module within the 1734 Point I/O series, designed to provide 16 discrete points—8 sink inputs for monitoring sensors or switches and 8 source outputs for controlling actuators, relays, or indicator devices. This integration of inputs and outputs in a single module reduces the need for separate modules, saving both panel space and installation time.

Equipped with screw terminals, the module ensures secure and vibration-resistant wiring, making it suitable for industrial environments with electrical noise or mechanical vibrations. Communication is handled via DeviceNet, allowing deterministic data exchange between the module and the
