An electropneumatic trailer control module (100; 300; 500) with a housing structure (100a; 300a; 500a) includes a manual brake pressure port (154) receiving a driver's brake demand pressure component, a spring-supported electropneumatic input valve (104) with at least two ports and being capable of switching between two positions (open or closed), an electropneumatic brake pressure port (144; 146) for receiving an electropneumatic brake pressure component from at least one independent pressure source (138; 140), and a relay valve (112) including a control port (110), a supply port (114), an outlet port (116), and a relief port (118). The spring-supported electropneumatic input valve (104) is retained in an open position when there is no electronic activation of the spring-supported electropneumatic input valve (104). A tractor protection module (124; 324; 524) is provided within the housing structure (100a; 300a; 500a) of the electropneumatic trailer control module (100; 300; 500).
