Allen Bradley 1756 ControlLogix I/O Modules Introduction

Allen-Bradley 1756 ControlLogix® I/O Chassis-Based Modules provide a full range of digital, diagnostic digital, analog, motion control, and specialty I/O to meet your application needs. You can use any of the Allen-Bradley 1756 ControlLogix® I/O modules in the local chassis of a ControlLogix controller or in a chassis linked to a ControlLogix controller across ControlNet™ or EtherNet/IP™ networks.

Each Allen-Bradley 1756 ControlLogix I/O module mounts in a ControlLogix chassis and requires either a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring. RTBs and IFMs are not included with the I/O modules. They must be ordered separately
