KCD2-STC-Ex1.HC SMART transmitter power supply - 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

• Low power dissipation

• Suitable for long field cables (> 1000 m)

• Terminal blocks with test sockets

• Up to SIL 2 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.

• Test sockets for the connection of HART communicators are integrated into the terminals of the device.

Application:

The device supports the following SMART protocol: 

• HART
