2.3 GW PL HART8+AI-BUS expansion module
The GW PL HART8+AI-BUS expansion module functions similarly to the GW PL HART8-
BUS expansion module, but also supplies the loop current to HART slaves, including loop
resistance, and adds the ability to transmit analog data. Up to five HART expansion
modules can be connected to the head station, allowing a maximum of 40 HART channels
to be operated in parallel. Each channel provides galvanic isolation from the HART signal.
