Transistor Output
• The transistor output of
the H5CX is insulated
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 H5CX.
Input Connections
The inputs of the H5CX-B are no-voltage (short-circuit or open) inputs or voltage inputs.
No-voltage Inputs (NPN Inputs)
Voltage Inputs (PNP Inputs)
Voltage Input Signal Levels
Note: 1. The DC voltage must be 30 VDC max.
2. Input resistance: Approx. 4.7 kΩ

Note: 1. The power supply and input circuit
are not isolated.
2. Terminals 1 and 6 are connected
internally.
3. Terminals 7 and 10 have the same
reset function. The same function will
be performed whichever terminal is
connected. Terminals 7 and 10 are
not connected internally, however, so
do not use them for cross-over wiring.
