Basic function: analog input 0/4 mA ... 20 mA, 1 and 2 channels.
The transmitter supply units are used for intrinsically safe operation
of 2- and 3- wire transmitters or for connection to intrinsically safe
mA-sources.
The 2- and 3-wire transmitters are supplied with power from the
transmitter supply unit.
For 2-wire transmitters the isolators transfer the HART
communication signal bidirectionally.
