A Relay Control Module is the device which permits the V-Net system to perform a host of automated tasks. It allows any information transmitted over the V-Net to be used to activate external high power devices such as a switch, solenoid, water pump, fan, or lights. Each module has two programmable output relays.
Each relay can have up to two separate (analog and/or digital) control signals that must be met before the relay is engaged. For example, one relay can be programmed to turn on a water pump only when a ‘Pump’ switch is on and the water temperature is above the programmed value, while the other relay can be used to activate an ignition kill switch only if the engine RPM is above a programmed value and the oil pressure is lower than a predetermined pressure. Relays are included.
