Overview
Ing surge protection switch input relay output signal isolator papalitan ne ing input signal ning switch contact o proximity switch keng relay output kapamilatan ning pamag-isolate.
Ing line fault detection lulual ya kapamilatan ning metung a relay at mipalabas ya kapamilatan ning LED light king babo ning module. Ing switch ning module magagamit ya para mamili keng phase ning channel ampo nung kailangan ing line fault detection function.
Ing produktung ini kailangan yang magsarili, at ing power supply, input ampo output terminals makabukud la.
