Schneider Electric 140NOE77101 Ethernet Module

The Schneider Electric 140NOE77101 Ethernet module is an Ethernet communication interface for Modicon PLC systems, enabling high-speed data exchange, remote monitoring, and connectivity with HMIs, SCADA systems, and other networked devices in industrial automation. It provides dual RJ-45 Ethernet ports (10/100 Mbps with auto-negotiation), supports Modbus/TCP, TCP/IP, and UDP/IP, is powered from the PLC backplane, mounts in a PLC rack slot on Modicon platforms, and is compatible with the Modicon M340/M580 families (platform dependent), with LED indicators for Link/Activity/Errors to assist network diagnostics. Common applications include production lines, packaging machines, building automation, and material handling, where reliable Ethernet connectivity supports distributed control and data logging; common replacements include Schneider 140NOE77102, 140NOC77101, and Allen-Bradley 1783-ETAP.
