General purpose auxiliary switching tasks
When it may not be suitable
This relay is not intended for switching high-power loads directly, such as large motors or heating elements, as it is designed specifically for auxiliary control signals. It is also not suitable for AC coil voltage applications, as it is strictly engineered for 24V DC operation.
Key specifications
Rated operational current: 10 A
Coil voltage: 24V DC
Contact configuration: 3 Normally Open (NO) and 1 Normally Closed (NC)
Mounting type: DIN rail or screw mounting
Compact modular design
How to use
The relay should be installed by a qualified professional within a suitable electrical enclosure. Mount the device onto a standard DIN rail or secure it using the provided screw mounting points. Connect the 24V DC control signal to the coil terminals, ensuring correct polarity. Wire the auxiliary contacts into your control circuit according to your specific system schematic, verifying that the load does not exceed the 10 A rating.
What to consider before purchase
Verify that your control system provides a stable 24V DC power supply.
Ensure the contact configuration (3NO/1NC) meets your specific circuit requirements.
Check the available space in your control cabinet for mounting.
Confirm that the environmental conditions are within the specified operating temperature range.
Usage recommendations
Always ensure the power supply is disconnected before performing any wiring or maintenance on the relay. Regularly inspect the terminal connections to ensure they remain tight and free from oxidation to maintain optimal electrical conductivity.
