Function

This isolated barrier is used for intrinsic safety applications. It drives SMART I/P converters, electrical valves, and positioners in hazardous areas.
Digital signals are superimposed on the analog values at the field or control side and are transferred bi-directionally.Current transferred across the DC/DC converter is repeated at terminals 1, 2 and 4, 5.An open and shorted field circuit presents a high input
impedance to the control side to allow line fault detection by control system.

If the loop resistance for the digital communication is too low,an internal resistor of 250 Ω between terminals 8, 9 and 11, 12 is available, which may be used as the HART communication resistor.
Sockets for the connection of a HART communicator are integrated into the terminals of the device.A unique collective error messaging feature is available when used with the Power Rail system.
