KFD2-SCD-EX1.LK模擬量輸出安全柵
This isolated barrier is used for intrinsic safety applications. It
drives SMART I/P converters, electrical valves, and
bers 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 and shorted field circuit presents a high b
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 and 9 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.
