HiC2025HC, SMART Transmitter Power Supply

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
