8.5. Analog inputs (4-20 mA)
Hardware-side:
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: 50 Ohm
Power supply for transducer: 12VDC / 200 mA
The sketches below show how the common transducer can connect to the IO module.
