Schneider 244LD Central control module

SCHNEIDER ELECTRIC Output Modules Overview

Schneider Electric offers a wide range of output modules for their Programmable Logic Controllers (PLCs) and Distributed Control Systems (DCS). These modules convert signals from the controller into the voltage and current required to control field actuators such as valves, motor starters, indicator lights, etc.

Product Detailed Description

• Function:

• Receives control signals from the PLC or DCS controller.

• Converts these signals into output signals required to drive external devices.

• Available in digital output (e.g., relay, transistor, triac) and analog output (e.g., voltage, current) types.

• Some modules also offer diagnostic functions to monitor output status and detect faults.

• Features:

• Modular design for easy installation and replacement.

• Wide range of voltage and current ratings to suit different load requirements.

• Opto-isolation to protect the control system from field-side voltage spikes and interference.

• Configurable output characteristics (depending on the model).

• Robust industrial design.
