FAQs
Is this relay compatible with non-Legrand intercom systems?
No, the 346210 is specifically designed for integration with Legrand bus-based intercom systems.
Does this module require a separate power supply?
The device draws power from the digital bus; however, always refer to your specific system configuration to ensure your power supply can handle the total load.
What does the 2 DIN designation mean?
This refers to the physical width of the unit. It takes up the space of two standard circuit breakers on a DIN rail.
Can I use this for high-voltage applications?
The relay is intended for auxiliary signal switching. Check the technical datasheet for the specific contact ratings before connecting high-load devices.
How do I configure the relay address?
Configuration is typically handled through your main system controller or software interface depending on your specific intercom model.
Troubleshooting
Relay fails to trigger external device
Verify that the relay is correctly addressed in the system configuration and check all bus wiring connections for continuity.
Intercom system shows a bus error
Ensure that the relay is properly seated on the DIN rail and that the bus cables are not short-circuited or reversed.
