Gateway Relay Outputs
The two relay outputs each accept a 2.5mm jack plug. These are individually controlled SPST
relay contacts. Comark provide 2 jack plugs for wiring external equipment to be activated by
the Gateway.
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.
