Connections

Terminal Arrangement

* The hold function is the same whichever terminal is connected. Terminals are not

connected internally, and so do not use them for cross-over wiring.

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.

• 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.
