HIC2031ES SMART Current Driver
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.
