The RA4890-D12 is a 1-phase Solid State Relay with SPST-NO contact, NORYL GFN 1 black housing and nickel-plated aluminium base plate. This panel mount relay features zero crossing switching mode and screw terminals. The zero switching relay with ant parallel thyristor output is the most widely used industrial SSR due to its multiple application possibilities. The relay can be used for resistive, inductive and capacitive loads. The zero switching relay switches ON when the sine curve just crosses zero and switches OFF when the current crosses zero.
