Designed for seamless side-mounting onto SR3 24V DC base units, this compact module bridges local control logic with modern plant networks via a 10\/100 Mbps RJ45 port supporting the industry-standard Modbus TCP protocol. Powered directly by the connected base relay, it enables remote monitoring, web server access, and SCADA integration without requiring complex gateway hardware.\u003c\/p\u003e\n\n  \u003ch3\u003eGlobal PLC Spare HUB's Insight\u003c\/h3\u003e\n  \u003cp\u003eIn compact automation systems where smart relays handle standalone machine control, operators often require remote diagnostic capabilities and SCADA data visibility without upgrading to a full-scale modular PLC. During a recent retrofit of a remote water-pumping skid, our engineering team integrated the \u003cstrong\u003eSR3NET01BD\u003c\/strong\u003e communication module to link an existing Zelio SR3 relay to the central control room. The Modbus TCP protocol implementation allowed real-time tag monitoring and remote parameter adjustments over Ethernet, eliminating costly onsite manual checks while preserving the existing relay configuration.\u003c\/p\u003e\n\n  \u003ch3\u003eTechnical Specification Matrix\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eManufacturer \u0026amp;
