The Infinitybox inMOTION NGX Door Control Module is a unique product in the commercial truck market.  It offers 2 h-bridge relays, 4-outputs and 8-inputs in a rugged and compact module.  It is intended to be mounted in a door to provide local control of power locks, power windows and low-current indicator lights.  It has 8 inputs to provide local control plus to send J1939 messages to other devices on the network.  This can simplify the wiring in doors for vehicle manufacturers and custom cab fabricators.  The only wiring required to go to the door is power, ground and the two CAN data wires.  This also has broad applications in custom vehicles where reversing and polarity control are needed.
