Details: KCD2-STC-1.2O

Function

This signal conditioner provides the galvanic isolation between field circuits and control circuits.

The device supplies 2-wire transmitters, and can also be used with current sources.

The device transfers the analog input signal to the control side 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.
