TRAILER CONTROL MODULE AND TRAILER CONTROL VALVE ARRANGEMENT

The invention relates to an trailer control module (1) for an electropneumatic braking system (100) comprising a trailer control valve arrangement TCV (20) at least connected to a supply connection (2) for receiving supply pressure (pS) and providing trailer control pressure (pTC) to a trailer working port (6), the TCV (20) comprising a breakaway valve unit (26) for switching between a supply state enabling fluid communication of supply connection (2) and a relay valve unit (30) and a breakaway state for throttling said fluid communication. The invention suggests the breakaway valve unit (26) including a switching member (54) subjected to a first pressure force F1 defined by pilot control pressure (pPC) and a second counteracting pressure force F2 defined by trailer control pressure (pTC), wherein the switching member (54) switches to the breakaway state in case of the second pressure force F2 falling below a predetermined threshold TB.
