Circuitry

All 16 channels have identical circuitry. As shown in Figure 4-2, the circuitry for a single I/O channel
consists of the following principal components:

•

An I/O ASIC

•

An output FET (Field Effect Transistor)

•

opto-coupler

•

A precision 250 ohm current sense resistor

•

A DC-to-DC power rectifier and filter

•

A communications pulse transformer
