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.
