The 6000 series, SSR-HS-1 , solid-state relays offer an energy-efficient SCR random current switching device with input voltage range as 142 to 280 VAC . Switching contacts configuration performed as SPST-NO with rated current 10 A and output voltage 292 to 280 VAC. Solid-state circuitry involves no moving parts and increases stability and reliability. Optically coupled circuit provides isolation between input and output circuits. Internal snubber helps protect the relays internal circuit from high voltage transients. Finger protected screw terminals help prevent an operator from touching live circuits.
