When it may not be suitable

This relay is not intended for high-power switching applications that exceed its rated current or voltage capacities. It is also not suitable for environments with extreme moisture, corrosive gases, or excessive vibration unless housed in an appropriate protective enclosure.

Key specifications

• Configuration: 4-pole
• Coil voltage: 24V DC
• Mounting type: 35mm DIN rail
• Status indicator: Integrated red LED
• Design: Complete plug-in relay

How to use

To install the relay, mount the base onto a standard 35mm DIN rail until it clicks securely into place. Connect the control circuit wires to the designated coil terminals and the load circuit wires to the contact terminals according to the wiring diagram. Once installed, apply 24V DC power to the coil terminals to activate the relay. The red LED will illuminate when the coil is energized, indicating that the contacts have switched.

What to consider before purchase

• Verify that your control system provides a stable 24V DC supply.
• Ensure the DIN rail space is sufficient for the relay dimensions.
• Check that the load requirements match the relay's contact ratings.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring or maintenance tasks to prevent electrical hazards. Regularly inspect the connections for tightness and ensure the relay remains free from dust and debris to maintain optimal performance.
