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.
