E series solid-state relays are DC input controlled, AC zero-crossing conduction, zero-crossing output type non-contact relays. Therefore, the ratio of di/dt is small, the starting performance is stable, the interference to the power grid is small, and the back electromotive force of inductive loads can be reduced during shutdown. It has certain protective effects on electrical appliances and solid-state relays. It is the preferred device for controlling general electrical appliances such as motors, heaters, and incandescent lamps.
The E4042-32G solid state relay is a DC‑input controlled, AC zero‑crossing on/off device designed for general loads such as motors, heaters, and incandescent lamps. It offers low di/dt, stable start‑up performance, reduced electromagnetic interference, and protection against inductive load back‑EMF.
Key specifications include a 3‑32 Vdc input control voltage, 420 Vac rated switching voltage, 40 A rated current, and operation within –30 °C to 80 °C. Installation requires screw‑mounting and appropriate heat‑sink selection, with the contact surface temperature limited to 80 °C. This manual is written in Chinese.
