KCD2-STC-EX1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

• 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 isolated barrier is used for intrinsic safety applications.

The device supplies 2-wire SMART transmitters in a

hazardous area, and can also be used with 2-wire SMART

current sources.

It transfers the analog input signal to the safe area as an

isolated current value.

Digital signals may be superimposed on the input signal in the

hazardous or safe area 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
