Solid-state relays such as "bestall" the E0142-14S series solid state relay is a DC input control, AC zero conduction, zero-turn-off-type non-contact relay output, input and output using optical isolation, fire-retardant epoxy potting materials engineering, Therefore, the ratio has a di / dt of small, smooth start-up performance, low on power radiated interference can be reduced when the back-EMF inductive load off, have a protective effect on the use of electrical appliances and solid-state relays, etc., is generally used to control electrical appliances, such as preferred device motors, heaters, incandescent.
