Requirement

General
The wiring of an analog measurement transducer is depends on its type and not on the
SM331 module.
5.3.2

Current transducer wiring - principle

Options
Depending on the current transducer you use, you have to modify the wiring of the power
supply. We differentiate between the wiring of a 2-wire current transducer and a 4-wire
current transducer.
Wiring principles of a 2-wire current transducer
This transducer type is supplied with power from the analog input module.
