v
Connect external devices to the EXT I/O terminal.
When connecting an external device, remove 9 mm - 10 mm of
the outer jacket of the cable and twist the cable core to prevent
the short circuit first.
Specification of cable (wire):
22 AWG - 28 AWG
Single core, twisted
* Check whether the stripped part of the
wire is not exposed and is securely con-
nected.
Important:
• Do not connect 2 wires or more directly to a terminal. When it is necessary to connect 2 or
more wires, use a splitter.
• Connect an external device with verifying that the ratings are within the specifications above.
• When using the EXT I/O terminals as the output terminals, ensure they do not cause signal col
-
lision with external signals.
