Series 9182
Output circuit
A, B: limit value relay A, limit value relay B,
configuration, refer to chapter "Limiting value settings for relays"
Line fault detection
The devices have line fault detection for the sensor circuit which can be activated or
deactivated.
The limiting values for the detection that are based on the sensor type are listed in the
following table:
*) When "Typ _ high Rq" thermocouples are used, no line breakage monitoring is carried
out, allowing connection of sensor lines at a resistance of more than 1 kΩ (loop).
The accuracy that can be achieved depends on the electrical line that is used.
**) Only for 3-wire potentiometer. Requirement: path resistance < 1/10 of the configured
resistance range of the potentiometer.
