Connections - SmartOutput module with SmartRelay 3
No. | Circuit board | Explanation |
|---|---|---|
1 | Out | Brownout detection: Open collector, connected to GND if supply voltage is sufficient. This output activates if the supply voltage at VIN falls below 10.0 VDC (±0.5 VDC). The earth connection is usually connected to the AUX relay's coil. If the supply voltage falls at VIN, the AUX relay activates before the other relay contacts activate unchecked due to the decreasing voltage. When the supply voltage is applied, the output does not activate until the module has fully initialised and relay contacts can no longer switch unchecked. |
