Details: KCD2-STC-Ex1.2O
Function
This isolated barrier is used for intrinsic safety applications.
The device supplies 2-wire transmitters in the hazardous area, and can also be used with current sources.
It transfers the analog input signal to the safe area as two isolated output signals.
Bi-directional communication is supported for SMART transmitters that use current modulation to transmit data and voltage modulation to receive data.
The output is selected as a current source, current sink, or voltage source via switches.
Test sockets for the connection of HART communicators are integrated into the terminals of the device.
