BX KNX Multifunction Actuator 8CH 16A (8 DIN) BX-MFB08
BX-MFB04 is a multifunction 8-channels actuator.The device provides the traditional switch functions previously described for the BX-ACT08 model and additional functions for opening and closing shutters, adjusting blinds, monitoring valves with a PWM algorithm and controlling fan coil devices (with 2 or 4 pipes).
The relays can be operated manually via a push button mounted on the front of the device, a green LED indicates the switching status of each channel. The power supply is provided from KNX bus through new tranceiver TPUART2 that provides better performance in terms of switching speed. The protection class of the package is IP20 and it is designed for installation on DIN 35mm.
Using the actuator to switch loads, all four outputs are parametrized individually.
Programmable contacts normally open or normally closed.
Manual operation with push buttons, LEDs indication and status transmission on the KNX bus.
Timer function for stairs light.
Logic functions on single outputs.
Relays status recovery after blackout and programmable startup conditions of the contacts.
The actuator works with pairs of interlocked relays to control shutters and blinds.
The number of interlocked pairs can be set by ETS parameters configuration.
Setting available on travel time and travel extra time in seconds, and stop time between two movements in milliseconds.
The actuator works with all 4 outputs to control fancoil.
The first three channels are interlocked and are used to drive the speed of the fans, the 4th channel drives the delivery valve.
