GS8535-EX-1 input 2 output Analog Input Isolated Barrier-上海辰竹仪表有限公司

GS8535-EX 1 input 2 output Analog Input Isolated Barrier

Intrinsically Safe Isolator: 2-wire HART transmitter, 3-wire transmitter, current source input isolated barrier(1 input, 2 outputs), provide isolated dc supplies for transmitters which located in hazardous area. Transfer 4~20mA signal(or current source signal) which generated by the transmitter form hazardous area to safe area separately, also allows bi–directional transmission of HART communication signals . The product needs an independent power supply.Input circuit,output circuit and power supply are each galvanically isolated.
