The XM® 440 Master Relay modules combine four relay inputs with XM bus master capabilities to support remote, shared, and voted relay operation for distributed XM measurement modules. Each module supports as many as twelve relays. Each relay is configured to actuate on “A out of B” voting logic, which can be applied to alarm status conditions broadcast from XM measurement modules located anywhere on the XM bus.
