TRIAC-LKG-C1
Triac Output Leakage Current (Surge Suppressor)
Mitsubishi Electric · MELSEC iQ-R I/O Module
¿Qué significa TRIAC-LKG-C1 ?
The triac output load fails to turn off due to a leakage current flowing through the triac module's built-in surge suppressor. This leakage current is significant enough to partially or fully energize the load, preventing it from deactivating completely when the output is commanded OFF.
Causas comunes
- Leakage current originating from the triac module's built-in surge suppressor.
- Increased line capacitance due to long wiring distances between the output module and the load, exacerbating leakage current effects.
