Figure 15: Input module - 1 transformer board
The input module consists of the main input board coupled together with an instr
ument transformer board. The
instrument transformer board contains the voltage and current transformers, which isolate and scale the
analogue input signals delivered by the system transformers. The input board contains the A/D conversion and
digital processing circuitry, as well as eight digital isolated inputs (opto-inputs).
The boards are connected together physically and electrically. The module is encased in a metal housing for
shielding against electromagnetic interference.
