Schneider Electric STBNIP2311 Terminal Block Assembly

STBNIP2311 is Schneider Electric’s standard dual-port Network Interface Module (NIM) for the Modicon STB family, delivering Ethernet connectivity and Modbus TCP/IP at 10–100 Mbps to link STB devices to an industrial LAN. It provides two RJ45 Ethernet ports for uplink and device connections and supports a scalable STB topology with one primary NIM and up to six extension segments. Schneider Electric lists STBNIP2311 as discontinued for commercialization on December 1, 2027, with end-of-service planned for December 31, 2035. In operation, the module enables standard Ethernet communications for Modbus TCP/IP across the STB network, facilitating reliable data exchange between base STB components, field devices, and supervisory systems over an Ethernet LAN.
