Analog digital conversion module, with time
synchronization (ADM)

Introduction

The Analog/Digital module has twelve analog inputs, 2 PC-MIP slots and 1 PMC
slot. The PC-MIP slot is used for PC-MIP cards and the PMC slot for PMC cards
according to table 451. The OEM card should always be mounted on the ADM
board. The UBM connects the ADM to the transformer input module (TRM).

Design

The Analog digital conversion module input signals are voltage and current from
the transformer module. Shunts are used to adapt the current signals to the
