1、 Product Overview
DC24V power supply provides isolated distribution power for on-site transmitters, while isolating and transmitting the current signals generated by the transmitters from the site to the control room, PLC, DCS, etc.
Input terminal interface current source, universal for two-wire and three wire transmitters; Internally, efficient magneto electric isolation technology is used to isolate the input, output, and power supply from each other, with characteristics such as high precision, high linearity, and low temperature drift.
■ DIN rail independent installation method.
