Overview

Ing analog input isolated safety barrier mamye yang isolated power supply para kareng adwang - ampo atlung wire transmitters kareng delikadung lugal. Ing 4~20mA signal a gewa ning transmitter o current source mipadala ya ibat keng hazardous area papunta keng safe area output, inya sa’t mag drive ya ing load keng safe area. Para kareng adwa - o atlung wire transmitters o current source signals, ining safety barrier susuportan ne ing bidirectional a komunikasyun ning Hart digital signal a maka-superimpose keng 4~20mA signal ampo atin yang wire breakage alarm function. Ing produktung ayni mangailangan yang independenting power supply, a maki makabukud a power supply, input, ampo output terminals.
