Function
This isolated barrier is used for intrinsic safety applications.
It drives a 4mA…20mA signal from the safe area to I/P
converters, electrical valves, and positioners located in the
hazardous area.
An open or high resistance field circuit presents a similar
resistance to the control side to allow line fault detection by
control system.
The voltage drop at the current input (terminals 7-, 8+ and 10-
, 11+) is lower than 2.5 V equivalent to an input resistance of
125 Ω at 20 mA
