The analog inputs are on the top of the IO module. They are marked with a blue
label. Through the help of the analog inputs, the IO module can read all common 4-
20 mA transducer in the analyzer directly. The IO module has a separate 12 V power
source, for the supply of the transducer. At the sketch below, the inputs and the
power supply, for the transducer are marked.
Information:
Internal Load:
