Product Introduction
This product has two application modes:
1. Provides an isolated power supply to field‑mounted two‑wire transmitters, receives the transmitter’s current output signal, and after isolation, outputs it to the system; the device’s power consumption is supplied by the output loop.
2. The current signal output by the system is isolated and transmitted to the field to drive field‑mounted valve positioners and other devices; power consumption is supplied by the input circuit.Technical Specifications
