HiC2031 SMART Current Driver

SMART Current Driver HiC2031 1-channel isolated barrier 24 V DC supply (bus powered) Current output up to 650 Ω load Low power dissipation SIL 2 (SC 3) acc. to IEC/EN 61508 This isolated barrier is used for intrinsic safety applications. It repeats the input signal from a control system to drive HART I/P converters, valve actuators, and displays 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 field circuit presents a high impedance to the control side to allow alarm conditions to be monitored by the control system. This device mounts on a HiC termination board.   Download Datasheet
