Extended Relay Card MCB 113
The MCB 113 adds 7 digital inputs, 2 analog outputs, and
4 SPDT relays to the standard I/O of the frequency
converter, providing increased flexibility and compliance
with the German NAMUR NE37 recommendations.
The MCB 113 is a standard C1-option for the Danfoss VLT
®
AutomationDrive FC 302 and is detected automatically
after mounting.

Illustration 7.17 Electrical Connections of MCB 113
Ensure galvanic isolation between the VLT
®
Automa-
tionDrive and the option card MCB 113 by connecting to
an external 24 V on X58/. If galvanic isolation is not
needed, the option card can be powered through internal
24 V from the frequency converter.
NOTICE
It is acceptable to combine 24 V signals with high-
voltage signals in the relays as long as there is 1 unused
relay in-between.
To set up MCB 113, use
parameter groups 5-1* Digital
