RXM Series Miniature Relays without LED

The Schneider Electric RXM4AB2BD is a professional-grade miniature plug-in relay from the Harmony (Zelio) Electromechanical range. It is widely used in industrial control panels, HVAC systems, and automation for switching multiple loads simultaneously.

 Features & Functionality

• Dual Status Indicators: Equipped with a green LED (lights up when the coil is energized) and a mechanical indicator (an orange flag that shows the physical contact position).

• Lockable Test Button: Features a blue push-button on the front for manual testing of the contacts. It includes a green flip-down cover that can lock the contacts in the "ON" position for troubleshooting.

• Plug-in Design: Designed to be used with a 14-pin socket (typically the RXZE2M114 or RXZE2S114M), allowing for quick replacement without rewiring.

• Compact Form Factor: Saves space in crowded control cabinets while still providing four independent poles.

Common Applications

• PLC Interfacing: Using low-power PLC outputs to drive higher-current industrial loads.

• Safety Interlocking: Coordinating multiple circuit states (e.g., ensuring a fan is on before a heater starts).

• Industrial Automation: Conveyor systems, packaging machines, and motor control logic.

  Important Considerations

  • Socket Requirement: This is the relay only. You will need a compatible 14-pin DIN rail socket to mount it.

  • Polarity: Since this is a DC coil model with a built-in LED, ensure you follow the terminal diagram for proper polarity (usually Terminal 13 for Negative and 14 for Positive) so the LED functions correctly.
