Pepperl+Fuchs Intrinsic Safety Barriers SMART Current Driver HiC2031 arrived.Time: 2020年04月16日
HiC2031: 1-channel isolated barrier, 24 V DC supply (bus powered), Current output up to 650 Ω load, Low power dissipation, Up to SIL 2 acc. to IEC 61508.
Signal type: Analog output
Functional safety related parameters
Safety Integrity Level (SIL): SIL 2
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.
