Mini 1-channel changeover relay module. Can be used in standalone mode (a push-button operates the relay directly), or in Velbus mode (input and relay are used as configurable Velbus channels)
Features:

1. 80A high inrush current changeover relay with potential free contacts
2. for switching capacitive, inductive or resistive loads
3. standalone mode: in standalone mode a push-button connected to the input operates the relay
   1. momentary or toggle mode can be selected by toggling the slide switch on the back
4. Velbus mode: in Velbus mode the module is connected to a Velbus domotics system
   1. the relay and input are used as Velbus output and input channels
   2. firmware upgradeable through the Velbus system
   3. CAN terminator switch with state detection
   4. bus error state indicated by led flashes
5. detection of power supply undervoltage indicated by led flashes (standalone and Velbus mode)
6. fire retardant ABS case with cuttable mounting brackets for screws and m3 bolts
7. leds for power supply, Rx (Receive), Tx (Transmit) and relay status
