Quad Triac Switch Card Electronics Kit

Extend the life span of the contact points in your relays with the Velleman Quad Triac Switch Card Kit. Relays are usually used to switch AC voltages by means of an electronic control, but when switching occurs too frequently or too quickly the life of the contact points is shortened considerably. This can be solved by replacing the relays with a triac. Using opto-couplers, the entire interface network remains electrically isolated from the voltage that has to be switched.

• 4 triac outputs: 1.5A (uncooled, 4A cooled)
• PCB dimensions 78 x 90mm
• Power supply 9Vdc/200mA
• Manufacturer's part K2634
