Functional Safety KFD2-SCD2-Ex*.LK, HiD2038
Product Description
HiD2038
The device repeats the input signal from a control system to drive HART I/P converters,
electrical valves, and positioners located in a hazardous area.
Current transferred across the DC/DC converter is repeated at the terminals 5a, 5b (1a, 1b).
The terminals 5b, 7a (1b, 3b) are used when no short-circuit detection is required.
Line fault detection of the field circuit is indicated by a red LED and an output on the fault bus.
The fault conditions are monitored via a Fault Indication Board.
This device mounts on a HiD Termination Board.
