Extended Relay Card MCB 113
The MCB 113 extends the I/O of the adjustable frequency
drive by seven digital inputs, two analog outputs, and four
SPDT relays. The extended I/O increases flexibility and
enables compliance with the German NAMUR NE37
recommendations.
The MCB 113 is a standard C1 option and is automatically
detected after mounting.

Figure 7.11 Electrical Connections of MCB 113
To ensure galvanic isolation between the adjustable
frequency drive and the option card, connect MCB 113 to
an external 24 V on X48. When galvanic isolation is not
required, the option card can be supplied through internal
24 V from the adjustable frequency drive.

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.
To set up 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
•
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.
•
Array [5] is relay 6.
