Introduction
Range of analog electronic modules
The range of analog electronic modules (EM) includes modules for measurement of voltage
and current. HIGH SPEED modules can be used for time-critical measurement of voltage
and current. HIGH FEATURE modules have a high resolution and precision.

4.2.1 Overview
Modules for connection of thermocouples and resistance thermometers or resistors are also
available.
The range also includes modules for connecting loads and actuators to current and voltage
outputs.
Analog value representation
Electronic modules with analog inputs
With the electronics module with analog inputs, continuously variable signals, such as those
occurring in temperature measurement and pressure measurement, can be acquired,
evaluated, and converted to digital values for further processing.
Electronic modules with analog outputs
With the electronics modules with analog outputs, digital values set by a controller can be
converted to a corresponding analog signal (current) in an analog output module and used to
control suitable actuators (setpoint input for speed controllers, temperature controllers and
similar).
