KCD2-STC-1信号隔离器

• 1-channel signal conditioner

• 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

• Housing width 12.5 mm

• Up to SIL2 acc. to IEC 61508

Function

This signal conditioner provides the isolation for nonintrinsically

safe applications.

The device supplies 2-wire SMART transmitters, and can also

be used with 2-wire SMART current sources.

It transfers the analog input signal as an isolated current value.

Digital signals may be superimposed on the input signal and

are transferred bi-directionally.

Selectable output of current source, sink mode, or voltage

output is available via DIP switches.

If the HART communication resistance in the loop is too low,

the internal resistance of 250 Ω between terminals 6 and 8

can be used.

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
