FC 300 Design Guide

10.8 MCB 113 Extended Relay Card

The MCB 113 adds seven digital inputs, two analog outputs and four SPDT relays to the standard I/O of the drive for increased flexibility and to comply
with the German NAMUR NE37 recommendations.
The MCB 113 is a standard C1 option for the Danfoss VLT® AutomationDrive and is automatically detected after mounting.
For information on mounting and installation of the option, please see
NOTE!
The MCB 113 can be used in all frame sizes. It can be installed at the same time as an MCO 305 (+ fan) in frame sizes A2, A3 and B3
(bookstyle), but not in the other frame sizes. Note that MCO305 cannot control the MCB 113.
Figure 10.5: Electrical connections of MCB 113
The MCB 113 can be connected to an external 24 V on X58/ in order to ensure galvanic isolation between the VLT® AutomationDrive and the option
card. If galvanic isolation is not needed, the option card can be supplied through internal 24 V from the drive.
NOTE!
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 set up the MCB 113, use Par. 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).
NOTE!
In par. 5-4* Array [2] is relay 3, array [3] is relay 4, array [4] is relay 5 and array [5] is relay 6
