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
for increased flexibility and to comply with the German
NAMUR NE37 recommendations.
The MCB 113 is a standard C1 option for the VLT
®
AutomationDrive and is automatically detected after
mounting.

Illustration 11.17 Electrical Connections of MCB 113
MCB 113 can be connected to an external 24 V on X58/ to
ensure galvanical isolation between the VLT
®
AutomationDrive and the option card. If galvanical
isolation is not needed, the option card can be supplied
through internal 24 V from the frequency converter.
NOTICE
It is OK to combine 24 V signals with high voltage
signals in the relays as long as there is one unused relay
in-between.
To setup MCB 113, use parameter groups 5-1* Digital input,
6-7* Analog Output 3, 6-8* Analog output 4, 14-8* Options,
5-4* Relays and 16-6* Inputs and Outputs.
NOTICE
In parameter group 5-4* Relay, Array [2] is relay 3, array
[3] is relay 4, array [4] is relay 5 and array [5] is relay 6
