Function and Application
The NJG1 series solid state relay (hereinafter referred to as the relay) uses an SCR structure internally, zero-crossing conduction, has an internal RC absorption circuit, and is filled with epoxy resin. It is widely used in electric furnace heating temperature control systems, CNC machinery, plastic machinery, food machinery, packaging machinery, textile machinery, petrochemical instruments, entertainment facilities, and other automation control fields, suitable for resistive, inductive, and capacitive loads.
