FineTek TXX2 Explosion-proof Safety Barrier Operations Manual |
Description
FineTek TXX2 Explosion-proof Safety Barrier Operations
The barrier is provided to isolate the power supply of a transmitter in a hazardous area, as well as transmit analog signal and digital signal generated by the transmitter to the safe side. The analog 4~20mA output signal can be converted into a 4~20mA isolated type. Moreover, it can read the HART digital signal or RS485 signal in the hazardous side, and isolates the digital output signal to the safe side.
