Use
The RXM21.1 PL-Link I/O-Block allows control of a single fancoil unit by a PXC3
room automation station via the PL-Link peripheral bus. It is optimized for fancoil
installation and control in terms of housing, connection terminals and I/O mix. The
PL-Link (PeripheraL-Link) is a two-wire bus system optimized for communication
between peripheral devices (sensors, actors) and the modular PXC3 room
automation stations in the domains or HVAC, lighting and shading.
