The outputs have been fitted with high accuracy current feedback that enables real time readout of the current consumption per channel. A new design of the NMEA connection provides galvanically isolated connection, without the need for a powered NMEA bus. The power consumption from the NMEA bus is ZERO for the Connect 50! The Connect 50 comes as standard with 11 input channels and 20 output channels. As an option it can be equipped with ports for additional galvanic isolated CAN and serial interface. In addition there is also an option to fit the Connect 50 with WiFi for wireless control and connectivity. Reverse polarity on two channels to control of tables, windows, hatches etc. is supplied as standard as well as capability of controlling and synchronizing window wipers. As on the EmpirBus NXT DCM, main power is connected by two M6 stainless steel bolts. The casing is IP65 rated, made from high-grade polycarbonate to deliver the robustness needed when operating under tougher conditions. Connecting equipment is done by two 16 way Molex MX150L connectors known from the EmpirBus NXT. This is a guarantee for long lasting connections without risk of corrosion or glitches – at the same time offering quick connection and simplified installation.
