When it may not be suitable
This relay is not intended for use in environments with extreme vibrations or high levels of corrosive dust, as these conditions may affect the mechanical integrity of the contacts. It is also not suitable for DC-specific applications, as the coil is designed exclusively for 230V AC operation.
Key specifications
Contact configuration: 1-pole (SPDT)
Switching current: 16A
Coil voltage: 230V AC
Contact material: AgNi
Socket compatibility: ECOR-1
How to use
To install the relay, ensure that the power supply is disconnected to prevent electrical hazards. Insert the relay into a compatible ECOR-1 socket, ensuring that the pins are correctly aligned with the terminal slots. Once seated, verify that the locking mechanism is engaged. Connect the control wiring to the coil terminals and the load wiring to the appropriate contact terminals according to the circuit diagram. After installation, perform a functional test to confirm that the relay switches correctly under load.
What to consider before purchase
Verify that your control circuit provides a 230V AC signal for the coil.
Ensure the load current does not exceed the 16A rating.
Confirm that you have the appropriate ECOR-1 socket for mounting.
Check the available space in your cabinet to ensure proper ventilation.
Usage recommendations
For optimal longevity, avoid exceeding the maximum switching capacity and ensure the relay is protected from moisture and extreme temperature fluctuations. Regular inspection of the socket connections is recommended to maintain low contact resistance.
