DIN rail electric energy meter KET-MDC-416

Modbuswith LCD display

The KET-MDC-416 allows the measurement of 6 continuous currents with values between -2500 A and +2500 A. It uses small Hall sensors connected with a 2m long cable as signal transducers. The display, with which it is equipped, allows sensor calibration via the integrated menu, displays the six readings in Amps, the reading in Volts, Power and Energy on the 6 channels. It features an RS485 interface with ModBUS RTU protocol compatible with the KET-RMB-211 ModBUS Bridge/Master and X-Monitor Gateways and any third-party ModBUS RTU master. The KET-MDC-416 is self-powered by the same voltage used for energy calculation.
