Overview
Ing isolated safety barrier a maki switch input transistor output, na mag isolate ya ampo mag transmit yang input signals ibat kareng switch contacts o proximity mag switch kareng delikadung lugal papunta keng safety zone gamit ing output transistor kapamilatan ning safety barrier. Ing pamangilala keng linya ning fault miraras ya kapamilatan ning LED keng babo ning module. Ing dial switch ning module ing gagamitan para i-set ing input ampo output in-phase o reverse control, ampo para i-enable o i-disable ing line fault detection alarm indication function.
Ing produktung ayni mangailangan yang independenting power supply, a maki makabukud a power supply, input, ampo output terminals.
