Siemens SIPROTEC 5

Measuring-Transducer Modules
Overview
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
The ports CH1 to CH4 of the measuring-transducer modules are Protective Extra Low Voltage circuits (PELV
circuits). For the connection to the measuring-transducer modules, the following conditions apply:
•
PELV circuits may be connected only to PELV circuits.
•
Ensure that the lines of PELV circuits are routed separately from the supply circuits.
•
Use shielded lines.
