Safety Barriers
LU-B22 Operation-End (Signal Output) Isolation Safety Barrier (2 In / 2 Out)
The LU-B22 safety barrier accepts two independent DC signals below 20mA or 10V, converts them into isolated standard process signals, and limits hazardous energy from entering the hazardous area through the intrinsically safe terminals. It has two independent input and output channels, each magnetically isolated between input, output and power supply.
