Wiring Input/Output Cables
The input/output cable has the following wires.
Wire the cable correctly. Incorrect wiring may damage the Smart Sensor.
(1) 24 VDC (
10%) power supply is connected to the power supply terminal.
±
Use a stabilized power supply separate from other devices and power systems for the Amplifier
Unit, when high resolution is required.
(2) The GND terminal is the 0 V power supply terminal. This terminal becomes the
common terminal for inputs/outputs other than linear output.
The 0 V terminal must be grounded in order for measurements to be performed correctly.
(3) The OPE1 indicator lights according to the judgment result or warning state.
(4) The OPE2 indicator lights according to the judgment result or warning state.
(5) The OPE3 indicator lights according to the judgment result or warning state.
(6) The linear output outputs a current or voltage in accordance with the measurement
result.
(7) The linear output GND terminal is the 0 V terminal for the linear output.
• This ground wire must be grounded separately from the other ground wires.
• Always ground the linear output terminal even when linear output is not used.
• When using Calculating Units, make sure that the linear GND lines of the Amplifier Units are
connected to each other.
(8) When this input is ON: The bank is switched using (9), (10), and (11).
(9) (8)=ON: Bank switching is executed.
(8)=OFF: The zero reset input is used to execute and clear zero reset.
(10)The timing input is for signal input from external devices.
(8)=ON: The bank is specified.
(8)=OFF: Use it for hold function timing. The sub-display indicates [TIMNG] while
the hold function timing is input.
(11)(8)=ON: The bank is specified.
(8)=OFF: The reset input resets all measurement processing and outputs. The sub-
display indicates [RESET] while the hold function reset is input. The linear and
judgment output signals are output according to the non-measurement settings. If
this reset input switches ON while the hold function is used, the state that was
active before the hold function was set is restored.
