mA output instruction manual
A single PR-23 system may have two sensors connected to one transmitter (DTR).
The DTR has two current outputs, but in some cases it is useful to have extra outputs
or remote outputs.
In the system above the DTR is connected to the mA output unit CPU (PR-10952)
with a cross-over Ethernet cable so that no Ethernet switch is required. The two
mA output units give a total of four outputs so that both the concentration and the
temperature can be indicated for both sensors.
If the Ethernet cable is replaced by a fiber connection, the distance between the
DTR and the output unit may be up to several kilometers (miles).
The system can be expanded to accommodate more DTRs by adding an Ethernet
switch and mA outputs as required.
