| Solid state relays (triacs output) |
|
Series GD Solid State Relays are AC relays,Triac Output. The triac version of the zero switching relay is an inexpensive solution for resistive loads. The zero switching relay switches on when the AC sine voltage just crosses zero,and switches off when the current crosses zero. |
