Pepperl+Fuchs isolated barriers SMART Current Driver HiD2038

Pepperl+Fuchs intrinsic safety barriers SMART Current Driver HiD2038.



Features
· 2-channel isolated barrier
· 24 V DC supply (bus powered)
· Current output up to 750 Ω load
· SMART I/P and valve positioners
· Line fault detection (LFD)
· Up to SIL 2 acc. to IEC 61508

Function: HiD2038
· This isolated barrier is used for intrinsic safety applications. It repeats a 4 mA ... 20 mA input signal from a control system to drive SMART I/P converters, valve actuators, and displays located in a hazardous area.
· Digital signals may be superimposed on the analog values in the hazardous or safe area, which are transferred bidirectionally.
· An open field circuit presents a high impedance to the control side to allow alarm conditions to be monitored by control systems.
· Line fault detection of the field circuit is indicated by a red LED and an output on the fault bus. The fault conditions can be monitored via a Fault Indication Board.
· This module mounts on a HiD Termination Board.
