Measuring-Transducer Modules
Overview
4.3.1
You can install the measuring-transducer modules in base modules or 1/3 modules (plug-in module positions E
and F) and in expansion modules with a CB202 plug-in module assembly (plug-in module position M, N, or P).
ANAI-CA-4EL
4.3.2
The ports CH1 to CH4 of the measuring-transducer modules are Safety Extra Low Voltage circuits (SELV
circuits). For the connection to the measuring-transducer modules, the following conditions apply:
•
SELV circuits may be connected only to SELV circuits.
•
Ensure that the cables of SELV circuits are routed separately from the supply circuits.
•
Use shielded cables.
