Programmable Relay contacts
Each panel includes two relays which are:
- Controlled by the matrix.
- Independent of the local panel function.
These relays can be assigned to any label(s) in the system, which will activate whenever a talk or listen is set to that label(s).
If you simply wish to trigger a relay, assign the relay to a control label. For more information, see your EHX documentation.
The relay can activate an external device, such as an applause light in a studio, a cue light, or a security door lock. Any programmable relay in the system can be activated from any panel in the system, including a direct-inward-access caller.
Matrix panel GPIO connector wiring shows the wiring of the relay contacts to the GPIO connector.
Both normally open and normally closed contacts are provided. They are rated at 1 Amp at 24 V DC. This relay is not designed for switching mains AC line voltage. To switch an external device running on mains AC line voltage, use an external relay (or other switching mechanism) activated by this relay.
