About the I/O cable
■ Wiring the I/O cable
The following shows the leads that comprise the I/O cable.
(1) Power supply
This connects the 24 VDC (±10%) power supply. When using a ZS-DSU with a PNP
output, the power supply terminal is also the common I/O terminal for all I/O except for
the linear output.Supply power from a DC power supply unit that has a countermeasure
(safety ultra-low voltage circuit) built-in for preventing high voltages from occurring.
Recommended power supply unit p.1-7
Wire the power supply separately from other devices. Wiring them together or placing
them in the same duct may cause induction, resulting in malfunction or damage.
(2) GND
The GND terminal is the 0V power supply terminal. When using a ZS-DSU with an
NPN output, the GND terminal is also the common I/O terminal for all I/O except for the
linear output.
(3) OUT0 (HIGH output)
This outputs judgment results (HIGH).
(4) OUT1 (PASS output)
This outputs judgment results (PASS).
(5) OUT2 (LOW output)
This outputs judgment results (LOW).
(6) OUT3 (ERR output)
This output turns ON when there is a Memory Card read/write error.
