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.
