FUNCTIONS

• SSR (Solid State Relay)

SSR consists only of semiconductor elements, and thus SSR

is free from arc discharge and chattering which are typical

with electromagnetic relays.

SSR has excellent durability against vibration, physical

impact, and environmental influences.

• Zero-Cross Function

SSR with zero-cross function turns on when AC power

voltage is near zero.

When input is provided in the middle of a wave cycle, SSR

delays switching until the next time the voltage becomes

near zero, thus limiting transient switching noise voltage

and rush current.
