Mitsubishi FX3G-40MR/DS SINK/SOURCE RELAY FX3G40MRDS

Description:

The Mitsubishi FX3G‑40MR/DS sink/source relay module is a programmable logic controller I/O unit used in industrial automation to provide discrete outputs for controlling field devices. It is commonly installed in Mitsubishi FX3G series PLC systems and control panels to interface PLC logic with relays, lights, solenoids, and actuators. Maintenance teams, OEMs, and system integrators use this module for I/O expansion, machine upgrades, and replacement of worn or failed output modules.

Applications:

The Mitsubishi FX3G‑40MR/DS module is widely used in manufacturing and process automation environments requiring reliable discrete output control. It is commonly found in conveyor systems, packaging machinery, assembly lines, material handling equipment, and automated production systems where sink/source relay outputs drive field loads such as contactor coils, indicator lamps, and solenoid valves.
