Overview
Ing signal ning vibration sensor milub ya keng isolated safety barrier, na maka-realize keng 1: 1 isolated transmission ning negative voltage signal output ning vibration sensor keng delikadung lugal papunta keng safe area, ampo malyari yang mag-transmit AC ampo DC signals, na atin matas a anti-interference function. Ing circuit mamye yang isolated power supply para kareng field instruments.
Ing produktung ini mangailangan yang independenting power supply, at ing power supply, input ampo output makabukud la.
