Click to see electrical hook-up details of the (TC22) Triac – List price $34.00
A Triac and Trigger Board work together to control the vibration rate of feeder bowls, inline feeders and vibratory hoppers.
The TC22 Triac is used for 115 volt and 230 volt applications rated up to 10 Amps.
In the unlikely event that a Triac fails, it most likely will fail “closed” meaning it will conduct full power regardless of the Trigger Board setting. If the output has full power with the green wire removed from terminal “G”. the Triac must be replaced.
Various Service Kits (depending on voltage and current requirements) are available that include both a Triac and a Trigger Board. Triacs and Trigger Boards can also be purchased separately if so desired.
