Measuring Transducers
Overview of Functions
Measuring transducers with an input rated at 20 mA can be used in the devices. 4 such inputs are available as
module ANAI-CA-4EL, which can be plugged into a communication module slot (for instance, port E or F). Up
to 4 such modules can be plugged in. Typically, slowly changing process variable such as temperature or gas
pressure are recorded with such 20-mA measured values and reported to the substation automation tech-
nology.
Structure of the Function
The measuring-transducer blocks are embedded in the Analog units function group and contain input and
output channels that are configurable independently of each other.

Structure/Embedding of the Function
Function Description
The 20-mA inputs typically transmit a value which represents a physical quantity such as a temperature or a
pressure. Therefore, the device must contain a characteristic curve that assigns the physical quantity to the
20-mA value. If the parameter
Range active
is not activated (no x in the check box), the function operates
over the range -24 mA to +24 mA. The setting of the range for the scaled value goes from a usable range of
-20 mA to +20 mA. The following figure shows an example.
