KL6771 | Bus Terminal, 1-channel communication interface, MP-Bus, master
The MP-Bus master terminal enables direct connection of MP-Bus slave devices. The MP-Bus was developed by Belimo for connecting valves, throttle valves, air valves and fire dampers for window ventilation systems. Up to sixteen field devices, eight drives and eight sensors can be connected to the KL6771. Process data exchange is fieldbus-independent. The Bus Terminal is configured and commissioned via TwinCAT function blocks. Status LEDs directly indicate the bus status. Several KL6771 terminals can be connected to the same Bus Coupler or Bus Terminal Controller.
