Transistor Output

• The transistor output of the H7CX is isolated from the internal
circuitry by a photocoupler, so the transistor output can be used as
both NPN and PNP output.

Power for load
• The diode connected to the collector of the output transistor is used
to absorb inverted voltage that is generated when an inductive load
is connected to the H7CX.
