Specifications
7.12.3 VLT
The MCB 113 extends the I/O of the frequency converter
with:
•
7 digital inputs.
•
2 analog outputs.
•
4 SPDT relays.
The extended I/O increases flexibility and enables
compliance with the German NAMUR NE37 recommen-
dations.
The MCB 113 is a standard C1 option and is automatically
detected after mounting.

required, the option card can be supplied through internal
24 V from the frequency converter.
NOTICE
To connect both 24 V signals and high-voltage signals in
the relays, ensure that there is one unused relay
between the 24 V signal and the high-voltage signal.
