12.2 Fundamentals of Analog Value Processing
12.2.1 Connecting Measuring Sensors
Introduction
You can connect different measuring sensors to the analog input modules,
depending on the type of module involved:
 Voltage sensor
 Current sensors as:
– Two-wire measuring transducer
– Four-wire measuring transducer
 Resistance-type sensor
In this chapter you will find out how to connect the measuring sensors and what to
watch for when doing so.
