- AO5049 operating terminal current output isolated safety barrier (two in, two 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.
◆ Usage environment
Working environment temperature: -20 ℃ to+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 ℃ to+80 ℃
◆ Panel indicator light
PWR: Green power indicator light, always on when the instrument is working normally;
