- AO5045 operating terminal current output isolated safety barrier (one in one out)
◆ Performance Overview
Convert the current signal from the safe area into a 4mA to 20mA current signal through isolation and output it to the hazardous area. On site equipment such as electrical converters and valve positioners that can control hazardous areas. The three terminal isolation of input, output, and power supply has the advantages of fast response, low power consumption, and good temperature characteristics.
◆ Precautions
The installation location must not have strong vibrations, as well as electromagnetic interference from signal terminals, power terminals, and space exceeding the third category of industrial site electromagnetic interference in the IEC61000-4 series, and there must be no harmful substances in the environment that can cause serious corrosion to metal and plastic parts.
◆ Usage environment
Working environment temperature: - 20℃～+60℃
Allowable relative humidity at work: 10% RH to 90% RH (40 ℃)
Allowable atmospheric pressure during work: 80kPa~106kPa
Allowable ambient temperature during storage and transportation: - 40℃～+80℃
◆ Panel indicator light
PWR： The green power indicator light is always on when the instrument is working normally.
