SMART Transmitter Power Supply, HiC2025HC

• 1-channel isolated barrier
• 24 V DC supply (bus powered)
• 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)
• SIL 2 (SC 3) acc. to IEC/EN 61508

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.

This device mounts on a HiC Termination Board.

The device supports the following SMART protocols:

• HART 
• BRAIN
