Range monitoring of signal type AI 0-10V:
– TX-I/O: short NEGATIVE signal –3.1 V (open circuit), 0.05 mA (shorted)
– DXR: permanently -1.5 V, 0.008 mA.
If a field device has no power supply, the negative voltage can damage any
polarized components (e.g. capacitors) in the field device.
3)
When the process value is outside the range, a fault message is issued.
