Indigo200 transmitters have 2 configurable relays (relay A and relay B). Both relays have configuration options for selecting the parameter that is used to control the relay, activation triggers, hysteresis, and error state behavior.
- 1
- Relay output on/off: Set to ON to enable relay output.
- 2
- Output parameter: The measurement that is used to control the relay. Options vary based on the type of the connected probe.
- 3
- Activate above:
When the measurement value exceeds the value set here, the relay activates.
See the different relay activation options described in Relay activation and hysteresis examples.
- 4
- Activate below:
When the measurement value falls below the value set here, the relay activates.
See the different relay activation options described in Relay activation and hysteresis examples.
- 5
- Hysteresis: Define a buffer value for relay deactivation (set the value according to the parameter selected for the relay). With hysteresis, an activated relay switches off only when the measured value crosses the relay activation/deactivation limit and the additional buffer value.
- 6
- Error output state: Select which state the relay is set to when an error occurs (on, off, or remains in its current state).
