Its integrated status indicator and protective circuitry provide clear operational feedback and safeguard the system against voltage spikes, contributing to a longer service life and enhanced reliability in complex control architectures.
Suitable for
Industrial automation and control systems
Signal isolation and level conversion
Electrical cabinet wiring and panel building
Automation of manufacturing machinery
This module may not be suitable for high-power switching applications that exceed its rated contact current or voltage limits. It is also not intended for use in environments with extreme moisture, corrosive gases, or excessive vibration unless housed within an appropriate protective enclosure.
Key specifications
Coil voltage: 24V DC
Contact configuration: 4 PDT (four-pole double-throw)
Connection technology: Push-in connection
Series: RIF-2
Width: 31 mm
To use the relay module, mount it onto a standard DIN rail within your control cabinet. Connect the control signal wires to the designated coil terminals and the load wires to the output contact terminals using the push-in connection points. Ensure that the supply voltage matches the 24V DC specification before energizing the circuit. The integrated LED indicator will illuminate when the relay coil is active, providing immediate visual confirmation of the switching status.
What to consider before purchase
Verify that the 24V DC coil voltage matches your control system output.
Ensure the 31 mm width fits within your existing DIN rail layout.
Check that the 4 PDT contact configuration meets your specific switching requirements.
Confirm the environment is suitable for standard industrial electronic components.
Usage recommendations: Always ensure that the power supply is disconnected before performing any wiring or maintenance tasks. Periodically inspect the connections to ensure they remain secure and free from debris to maintain optimal electrical contact.
