Pepperl+Fuchs SMART Transmitter Power Supply KCD2-STC-Ex1.ES
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.
The device transfers the analog input signal to the non-hazardous area as an isolated current value.
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 DIP switches.
A fault is signalized by LEDs and a separate collective error message output.
Test sockets for the connection of HART communicators are integrated into the terminals of the device.
The device supports the following SMART protocols:
- HART
