Gateway Relay Outputs
The two relay outputs each accept a 2.5mm jack plug. These are individually controlled SPST relay contacts. Comark
can supply jack plugs for wiring external equipment to be activated by the Gateway.
The maximum lead length for the relay outputs is 30m.
Ensure that any external equipment presents only a low voltage on the jack so as to prevent any
chance of personal injury due to electric shock should the jack plug become disconnected.
