SMART Transmitter Power Supply/Current Driver
- 4-channel isolated barrier
- 24 V DC supply (bus powered)
- Analog in or analog out signals
- Sink and source mode outputs
- SMART pass-through
- Up to SIL 2 acc. to IEC 61508
This isolated barrier is used for intrinsic safety applications. It operates as a SMART transmitter power supply or as a repeater. Bi-directional communication is supported for SMART transmitters that use current modulation to transmit data and voltage modulation to receive data. The outputs are fully isolated from the inputs, the power supply, and each other. An open field circuit presents a high impedance to the control side to allow alarm conditions to be monitored by control systems. This module mounts on a HiD Termination Board.
