Overview
Ing pamaglipat input transistor output Deng makabukud a safety barriers magpadala lang input signals ibat kareng switching contacts o proximity switches keng delikadung lugal kapamilatan da reng safety barriers a makabukud keng ligtas a lugal a maki transistor outputs. Ing input kontrolan ne ing passive transistor output a maki resistive a katangian. Ing output atin yang apat a defined states: short-circuit alarm resistance ≤ 240 Ω, 1-signal 1.4KΩ ≤ resistance value ≤ 1.6KΩ, 0-signal 13KΩ ≤ resistance value ≤ 14KΩ, ampo ing broken alarm resistance > 1.6KΩ. Ing output characteristic ayni magreact ya keng line state keng signal line. Deng dip switches ning module magagamit la para i-set ing input ampo output keng parehung direksyun o reverse control, ampo para i-set ing line fault alarm indication function. Ing produktung ayni mangailangan yang independenting power supply, a maki makabukud a power supply, input, ampo output terminals.
