MRK 10 PC Board for Heidelberg Printmaster

Description

This is the motor control board, or MRK board of a Heidelberg Printmaster press. This one is an "MRK 10" as you can see in the pictures.
It gets speed and direction information from the ZTK board, and both 15V DC and 8V DC power from the TRK.
If you are getting error codes in the 15.something range, this is one of the potential problem areas.
This electrical "item" will be shipped in a sealed, static free, see through bag. If the seal is broken, you own it! No returns will be allowed once the seal has been broken. Make sure it is exactly what you want before opening the bag.
