Danfoss VLT AutomationDrive Design Guide

10.8 MCB 113 Extended Relay Card
The MCB 113 adds 7 digital inputs, 2 analogue outputs
and 4 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 Mounting of Option Modules in Slot C1

Illustration 10.9 Electrical connections of MCB 113
MCB 113 can be connected to an external 24V on X58/ in
order 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 24V from the drive.
NOTE
It is OK to combine 24V 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).
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
