The 27HMI v2 is a compact round CAN-bus display. It shows real-time J1939 parameters, warnings and system messages on a sharp monochrome screen with three dead-front status LEDs. Our configuration tool programs it to send and receive any CAN message, so one part number can be an engine monitor, a level gauge, a load indicator or a controller. It is sealed to IP67 at the front and fits a standard gauge hole.
