Protection: none; the maximum current al-
lowed for the input is 25 mA.
Digital inputs: 3 inputs which can be set via configuration
parameter for normally open or normally closed contact
(door switch, multipurpose and multipurpose 2).
5 VDC, 2 mA digital inputs (free of voltage)
Power supply: none
Protection: none.
Digital outputs: up to 6 outputs:
- two 30 res. A @ 250 VAC SPST electromechanical relays
(compressor and evaporator fan)
- one 16 res. A @ 250 VAC SPST electromechanical relay
(defrost)
- one 16 res. A @ 250 VAC SPST electromechanical relay
(room light; not available in EVB1204 and EVB1214)
- one 8 res. A @ 250 VAC SPST electromechanical relay
(which can be set via configuration parameter for room
light, demisting heater, auxiliary output, alarm output,
door heater, neutral zone operation heater, condenser
fan, compressor 2, defrost 2, evaporator fan 2, pump
down valve, on/stand-by or man in room; only avail-
able in EVB1204 and EVB1214)
- one 8 res. A @ 250 VAC SPST electromechanical relay
(which can be set via configuration parameter for de-
misting heater, auxiliary output, alarm output, door
heater, neutral zone operation heater, condenser fan,
compressor 2, defrost 2, evaporator fan 2, pump down
valve, on/stand-by or man in room; not available in
EVB1204 and EVB1214)
- one 8 res. A @ 250 VAC SPDT electromechanical relay
(which can be set via configuration parameter for de-
misting heater, auxiliary output, alarm output, door
heater, neutral zone operation heater, condenser fan,
compressor 2, defrost 2, evaporator fan 2, pump down
valve, on/stand-by or man in room; not available in
EVB1204 and EVB1214).
The device ensures a reinforced insulation among each con-
nector of the digital outputs and the remaining parts of the
device.
