Working Principle The board receives analog feedback signals from DC motor armature current shunts and excitation voltage sensors, conditions these signals through precision operational amplifier circuits, and provides optical isolation before transmitting to the Mark V control processor. Control commands from the processor are similarly isolated and transmitted to power conversion firing circuits. Digital I/O channels handle status signals and protection interlocks.

Installation Requirements

• Install in Mark V control cabinet DC drive section
• Ensure proper grounding to prevent electromagnetic interference
