Product Information

Full details

This Schneider Electric RXG Interface Relay (RXG22BDPV) is designed for industrial automation professionals needing reliable pre-assembled interface solutions. Its key benefit is providing 2 CO contacts with integrated diode protection for safe PLC interfacing. A potential caveat is its specific 24VDC operating voltage, requiring careful power supply matching. This module simplifies control panel wiring with its lockable test button, LED indicator, and secure screw terminal connections.

FAQs

What is the purpose of the integrated diode protection?

The integrated diode protects the relay coil and the control circuit (e.g., PLC output) from damaging voltage spikes generated when the coil is de-energized (back EMF).

Can this relay be used with AC control signals?

No, this relay is specifically designed for 24VDC coil operation. Using an AC signal can damage the relay.

What is the maximum load current the contacts can handle?

Each of the 2 CO contacts is rated for a maximum of 5A.

How do I manually test the relay operation?

You can manually energize the relay using the lockable test button. Push the button to energize the coil. It can be locked in the energized or de-energized state for testing or maintenance.

What does the IP20 rating mean?

IP20 means the relay is protected against solid objects greater than 12.5 mm (like fingers) and has no special protection against water. It should be installed in an environment protected from water ingress.

What standards does this relay comply with?

It meets IEC, UL, CSA, and RoHS standards, indicating broad international compliance and suitability for various global markets.

Can I use this relay with a 12VDC power supply?

No, this relay is specifically designed for a 24VDC coil voltage. Using a different voltage may result in malfunction or damage.

Troubleshooting

Relay does not energize when control signal is applied.

Verify the control voltage is exactly 24VDC. Check wiring connections to the coil terminals (A1/A2). Ensure the control signal is present and of the correct polarity. Confirm the test button is not locked in the off position.

Relay does not de-energize when control signal is removed.

Check for any residual voltage on the control input. Ensure the test button is not locked in the on position. Verify the coil is not shorted.

Contacts are not switching (no continuity or always continuity).

Ensure the relay is properly energized or de-energized. Check that the load current does not exceed the 5A rating. Inspect wiring to the contact terminals (0, 1, 2, 3, 4).

LED indicator is not lit.

Verify the control voltage is applied to the coil. Check the wiring to the coil. The LED may be integrated with the coil circuit; if the relay functions but the LED does not, the LED itself might be faulty.

Pros and Cons

Pros

  • Compact, pre-assembled design saves installation time.
  • Integrated diode protection enhances system reliability.
  • Lockable test button provides safe manual operation.
  • Clear LED indicator for quick status checks.
  • Meets various international standards (IEC, UL, CSA, RoHS).

Cons

  • Fixed 24VDC operating voltage may limit compatibility with other voltage systems.
  • IP20 rating requires installation in a protected enclosure.
  • Screw terminals may require specific torque settings for optimal connection.

Setup, Compatibility & Care

Setup:

  1. Ensure the power supply matches the coil voltage (24VDC).
  2. Connect the control voltage to the coil terminals (A1 and A2) according to the wiring diagram.
  3. Wire the load circuits to the common (1, 3), normally open (2, 4), and normally closed (0, 1) terminals of the CO contacts.
  4. Securely tighten all screw terminals to the recommended torque to ensure a solid connection.

Compatibility:

  • This relay is designed for 24VDC control circuits.
  • It is compatible with PLC outputs and other control systems providing a suitable 24VDC signal.
  • Ensure the load current does not exceed the 5A rating per contact.

Care:

  • Keep the relay clean and free from dust and moisture. Use a dry cloth for cleaning.
  • Ensure adequate ventilation around the relay, especially when mounted in enclosures.
  • Periodically check terminal connections for tightness.
