| Symptom | Likely Cause | Solution | |---------|--------------|----------| | LED on, but load does not activate | Welded output contacts or broken wiring | Check continuity with power off. Replace module if contacts are shorted. | | LED off, but load is active | Stuck relay armature or leakage current | Test input voltage. If zero, replace module. | | Intermittent switching | Loose terminal screws or insufficient coil voltage | Torque terminals to 0.5 Nm. Verify supply voltage is within ±10% of nominal. | | Overheating | Exceeding current rating or poor ventilation | Reduce load to ≤80% of rated current. Add forced cooling if ambient >50°C. | | False triggering on adjacent channels | EMI crosstalk or common ground issue | Separate input and output wiring bundles. Use shielded cables for low-level signals. | How does SGKI 078 stack up against other switching solutions? Here is a quick comparison: And as always, when in doubt, consult the
