	Pepperl + Fuchs KCD2-STC-Ex1.ES SMART Transmitter Power Supply Isolated Barrier
	Features
	• 1-channel isolated barrier
	• 24 V DC supply (Power Rail)
	• Input for 2-wire SMART transmitters and current sources
	• Output for 4 mA ... 20 mA or 1 V ... 5 V
	• Sink or source mode
	• Line fault detection (LFD)
	• Housing width 12.5 mm
	• Up to SIL3 acc. to IEC 61508
	
	 
	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 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 acc. to NAMUR NE44 and a
	separate collective error message output.
	Test sockets for the connection of HART communicators are
	integrated into the terminals of the device.
	
	 
	Application
	The device supports the following SMART protocol:
