Triac Output Leakage Current (Surge Suppressor)

What does TRIAC-LKG-C1 mean?

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.

• 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.

1. 1

   Connect a resistor in parallel across the load terminals. This resistor provides an alternative path for the leakage current, ensuring the load completely turns off.
