KCD2-STC-Ex1.2O模拟量安全栅
• 1-channel isolated barrier
• 24 V DC supply (Power Rail)
• Input for 2-wire SMART transmitters and current sources
• Signal splitter (1 input and 2 outputs)
• Dual output 0/4 mA ... 20 mA or 0/1 V ... 5 V
• Terminal blocks with test sockets
• Up to SIL2 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 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.
Application
The device supports the following SMART protocols:
• HART
• BRAIN
• Foxboro
