Details: KCD2-SCD-Ex1.HC.SP

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.

Bi-directional communication is supported for HART devices.

An open field circuit presents a high impedance to the control side to allow alarm conditions to be monitored by control systems.

Test sockets for the connection of HART communicators are integrated into the terminals of the device.
