2.5 Expansion card

From version 3.3.0, an I/O expansion card can be used to provide additional
analogue and digital channels, ideal when there is a high number of
compressors and corresponding alarms, or with complex heat recovery
systems that require of numerous temperature sensors in the water and
CO2 circuits (see technical leafl et +0500059IE for the product's electrical
and physical specifi cations). The universal inputs/outputs (marked U on
the connection diagram) can be confi gured by pRack pR300T to connect
active and passive probes, digital inputs, analogue and PWM outputs, up
to a total of 10. A further 6 digital outputs are also available.

The expansion card is connected to the pRack pR300T via port J26 FBus
on the pRack, the same used for connecting an external driver, and port
J6BMS on the expansion card via RS485
Only one expansion card can be used for each compressor rack and the
expansion card can only be connected to the board with pLAN address 1:
