Figure 22. General channel schematic
A general schematic representing each of the four channels is shown
above in Figure 23. Each channel has an input resistance of
approximately 100k ohms and is diode isolated from Relay Driver
power and ground. A shunt (approx. 0.6 ohms) measures channel
current.
