Parallel I/O connection
Description
This outputs the measured value from -10 V to +10 V as the voltage value.
When measurement not possible: Approx. 10.8V (default value, can be selected by user)
At alarm: Approx. 10.8V
This outputs the measured value, from 4 mA to 20 mA as the current value.
When measurement not possible: Approx. 21 mA (default value, can be selected by user)
At alarm: Approx. 21 mA
Description
Judgment result HIGH (HIGH threshold value < measured value) is output.
Judgment result PASS (LOW threshold value  measured value  HIGH threshold value) is
output.
Judgment result LOW (LOW threshold value > measured value) is output.
Description
This turns ON when there is a system error.
Description
This turns ON during sampling with the hold function enabled.
It allows you to check whether or not the self-trigger is functioning correctly.
It also turns ON during bank switching.
Description
This turns ON when the sensor is ready for measurement.
This output is interlocked with the ENABLE indicator.
Description
This is used to execute and clear a zero reset.
