HiD2025, SMART Transmitter Power Supply
[ Backorder Available, Ships in 3+ Weeks ]
SMART Transmitter Power Supply, HiD2025
- 1-channel isolated barrier
- 24 V DC supply (bus powered)
- 2-wire SMART transmitter
- Output for 4 mA ... 20 mA or 1 V ... 5 V
- Low power dissipation
- Up to SIL2 acc. to IEC 61508
This isolated barrier is used for intrinsic safety applications. It provides 2-wire SMART transmitters with power in the hazardous area, and repeats the current to drive a safe area load. Bi-directional communication is supported for SMART transmitters that use current modulation to transmit data and voltage modulation to receive data. The output is isolated from the input and are referenced to the power supply common. This module mounts on a HiD Termination Board.
The device supports the following SMART protocols:
- HART
- BRAIN
- Baily (only SST-02 communication, e. g. BCN series)
- Foxboro
