KCD2-STC-1.2O信号分配器
• 1-channel signal conditioner
• 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 SIL 2 acc. to IEC 61508
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.
Application
The device supports the following SMART protocols:
• HART
• BRAIN
• Foxboro
