An electropneumatic trailer supply module, for an electropneumatic parking brake system for a tractor vehicle/trailer combination, includes a supply connection configured to connect a compressed air supply, a trailer supply connection configured to deliver a supply pressure for a trailer vehicle, a pneumatically controlled main valve unit configured to provide the supply pressure to the trailer supply connection, and an electropneumatic pilot control unit configured to select at least a first control pressure at the pneumatically controlled main valve unit. When the first control pressure exceeds a predefined first threshold value of the pneumatically controlled main valve unit, the supply pressure provided to the trailer supply connection can be selected. When the first control pressure falls below the predefined first threshold value of the pneumatically controlled main valve unit, the trailer supply connection is configured to be vented.
