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 and 2.
An open field circuit presents a high input impedance to the
control side to allow lead breakage monitoring by control
system.
If the loop resistance for the digital communication is too low,
an internal resistor of 250 Ω between terminals 6 and 8 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.
