• The functions of the inputs and outputs depend on the particular application!

• 8 digital inputs for e.g. operating messages or fault messages and 230V~ control commands

• 4 relay switching outputs 230V~

• Integrated power supply for CAN bus and relay

• No parameters to be set on the device

• Module number setting with user-friendly coding switch

Wurm CAN field bus (F-BUS) application

Rack module for HVx-G3/G4

• Evaluation of cross-rack functions and signals via digital inputs and digital outputs

• Connection to master module via F-BUS

Defrost module for HKS-G3/G4

• 1 defrost module per F-BUS possible

• Forced cooling for cold location groups (hot gas and cool gas defrost)

• Implementation of additional safety functions for the associated rack by suppressing the cooling command for all cold locations in a defrost group

• Fixed assignment of outputs K 1...K 3 for cold location defrost within a defrost group

• Connection to master module via F-BUS
