■ Description
PR308T21ESZ reinforced insulation type Solid
State Relays (SSR) are an integration of an infrared
emitting diode (IRED), a Phototriac Detector and a
main output Triac. These devices are ideally suited for
controlling high voltage AC loads with solid state reli-
ability while providing 3.0kV isolation (V
iso(rms)
) from in-
put to output.
