Fig. 2.1.1-5: MP-Bus circuit
Up to 8 slaves can be connected to one master.
MP-Bus-enabled actuators are designed using MFT (Multi Function
Technology). Damper drives, MFT(2) valve drives, MFT fire prevention
damper drives and VAV compact controllers, as well as the Belimo FLS
window ventilation system are available.

Bus connectors on the Internet at:
One sensor can be connected per MFT(2) drive. This can be a passive resistive
sensor (NTC, Pt1000, Ni1000 or Ni1000 Landis & Staefa), an active sensor
(e.g. with 0 ... 32 V DC output), or a switch contact (on/off). The analogue
signal from the sensor is digitized with the drive and passed on to the MP-Bus
master module via the MP-Bus.
