Features universal input and output module (Wurm CAN communication bus (C-BUS))

• The functions of the inputs and outputs depend on the respective application!
• 8 operation or fault messages and control commands at 230V~
• 4 relay switch outputs at 230V~
• Integrated power supply for CAN bus and relay
• No parameters to be set on the device
• Setting the module number by user-friendly coding switch

Features of defrost module (Wurm CAN field bus (F-BUS) of HKS-G3/G4)

• One defrost module per F-BUS is possible
• Forced cooling for cold location groups (hot gas and cool gas defrosting)
• By suppressing the cooling command of all cold locations of a defrost group, additional safetyfunctions can be implemented for the associated compound
• The digital outputs (K1...K3) are set if a cold location within a defrost group is defrosting
• Integrated power supply for CAN bus and relay
• Connection to master module by F-BUS
