Schneider Electric 3020-ECM-RM PowerLogic Ethernet Communication Module

Schneider Electric’s Square D PowerLogic 3020-ECM-RM Ethernet Communication Module is an Ethernet interface for PowerLogic Class 3020 devices, enabling networked data exchange and daisy-chain configurations with ECM-2000 and other PowerLogic units. It is powered from 90–264 VAC, 50/60 Hz, and provides 10/100 Mbps Ethernet connectivity for field-level monitoring and integration with building management or SCADA systems. The ECM-RM supports a four-wire daisy-chain protocol on its daisy-chain port, linking SyMax/PowerLogic, Modbus and JBUS devices to create scalable network architectures. This module facilitates expanding a PowerLogic network to add Ethernet communication and remote monitoring capabilities across multiple meters or controllers in data centers, commercial buildings, and industrial facilities.
