External Control (
EXT. I/O)
WARNING
To prevent an electric shock or damage to the equipment, always observe the
following precautions when connecting the cables to external control terminal
connectors.
•
Always turn OFF the instrument and any devices that are connected before
making connections.
•
Be careful to avoid exceeding the ratings of the external control terminal
connectors.
•
During operation, a wire becoming dislocated and contacting another
conductive object can be a serious hazard. Use screws to secure the external
control terminal connectors.
•
Ensure that devices and systems that are connected to the external control
terminal connectors are properly isolated from one another.
CAUTION
To keep connected devices from malfunctioning, use a shielded cable of no more than
3 m in length to connect external devices to the instrument.
Using the external control terminals on the rear of the instrument enable the following.
• Output measurements finished signals (EOM signals) and judgment results signals (PASS/FAIL),
etc., from the instrument to external device.
• Input START signals, etc., from an external device to the instrument to control the instrument.
Rear
Output or input signals
All signals are isolated from the measuring circuit and the ground (earth). (Common I/O terminals
are shared)
The instrument input circuit can be switched so that it can support sinking current output (NPN) or
sourcing current output (PNP).
Reference: “10.2 Sinking Current (NPN) / Sourcing Current (PNP)” (p. 135)
Check the input rating and internal circuit configuration, and then understand the safety precautions.
After that, connect the control system and use it in a correct manner.
Reference: “Internal circuit configuration” (p. 139)
