The FC13 satellite is one of the possible building BUS expansions for the PB control units. It is equipped with 8 random variable or fixed reference inputs, which are available on a terminal block. Its small size allows it to be housed in junction boxes installed in the various environments to be protected. The BUS address is programmed by dip switches. It has LED indicators for the CPU and BUS activity status and for the status of the self-resetting electronic protection fuse on the power supply for the inputs.

Resistive balancing other than the PB standard can be selected simply using dip switches. It can therefore interface to sensors that were previously connected to other control units, leaving the existent resistors. In this way, the control unit can be replaced while minimising the costs and system downtime.
