Detail LU-B22 (TypeF) Barriers

LU-B22 (TypeF) Barriers

1.Technical Parameters:
1)main functions and features
● compact and insert-mounting
● output circuit Intrinsic Safety, [Exib]ⅡC if suitably certified.
● The supply of power to two independent 2-wire transmitters
● Transfer the DC signal to isolated standard process signal, and prevent hazardous energy from the instrinsically safety terminal into the hazardous area.
● With power indicator, Zero & Span adjustment for output signal
● Two independent input channels & output channels, each channel ”Input, output and power supply “are isolated from each other
