Description
Product Details
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.
