M-Bus Master Option Card
The M-Bus Master Option Card is an extension for all Tridium Jace and M2M devices. This card turns the Jace into a compact and easy to configure Smart Metering System. It can connect up to 10 M- Bus devices, while protecting the Jace from short-circuits on the bus. No additional parts are needed - the card uses the built-in serial port and power supply on the Jace.
