This isolated barrier is used for intrinsic
safety applications. It drives a voltage or
current signal from the safe area to I/P
converters, electrical valves and
positioners located in the hazardous
According to a unique ordering code, this
barrier is designed to provide various

inputs and outputs of voltage and current.
