External Analogue Input
The analogue terminals are located on the left hand side of the PCB near the
top.
The use of 4
– 20mA and 0-10V transducers
require the slide switches to be placed to
match the input. This allows the system to
read the correct input from the transducers.
Volts =0-5VDC,0-10VDC etc
mA= 0-20mA,4-20mA etc
4-20 mA is a standard analogue signal from a level transducer.

To use this input, note the wiring requirements on the PCB. A regulated 24VDC power
supply is available on board for 2-wire configuration.
