Product details
1、 Product Overview
The SNDED-3I three-phase AC current transmitter converts the three-phase AC current signal from the AC transformer into a standard process signal, which is used for central monitoring of motors, pumps, or heating networks in DCS, monitoring power supply lines and their currents.
High reliability isolation of input, output, and power ports.
