SMART Current Driver HiC2031ES

• 1-channel isolated barrier
• 24 V DC supply (bus powered)
• Current output up to 650 Ω load
• HART I/P and valve positioner
• Low power dissipation
• Line fault detection (LFD)
• Up to SIL 3 acc. to IEC/EN 61508

This isolated barrier is used for intrinsic safety applications.

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.

Digital signals are superimposed on the analog values at the field side or control side and are transferred bi-directionally.

An open or short field circuit presents a high impedance to the control side to allow alarm conditions to be monitored by the control system.

Line fault detection of the field circuit is indicated by a red LED and an output on the fault bus.

This device mounts on a HiC termination board.
