xLogic is the compact micro-PLC and smart relay product line developed by RIEVTECH Electronic . Where a full-size PLC is overkill and a timer-relay stack is not enough, xLogic controllers fill the gap: programmable, connected, and small enough to fit in any cabinet.

Traditional automation relied on racks of timers, counters and contactors — hard to change and impossible to monitor remotely. We designed xLogic to replace those components with a single DIN-rail controller that is programmed visually, communicates over standard industrial protocols, and costs about the same as the parts it replaces.

Since the first release, the product line has grown around three ideas: simplicity (visual FBD programming), connectivity (built-in web server, free EasySCADA software, and native Modbus, MQTT and BACnet), and affordability (a realistic price for OEM machine builders and small automation projects).

The xLogic family covers:

• SR Series — Smart relay / nano PLC : the economical entry point for replacing timers and contactors.
• PR Series — Micro PLC with LCD + keypad : more I/O, high-speed counting and expanded program capacity for demanding machines.
• Ethernet / WiFi / 4G models : remote monitoring and control over Modbus, MQTT and BACnet for machines that must be connected.
• HC Series — HVAC controller / DDC : purpose-built for fan coils, ventilation and building automation.
• Expansions & accessories : digital/analog I/O modules, PT100 modules, battery and memory modules, and programming cables.

Every xLogic controller is programmed with free software — no licensing cost : xLogicSoft for visual function block diagram (FBD) programming, and xLadderSoft for traditional ladder programming. No prior PLC experience is required; a first program can be running in minutes.

xLogic gives you two ways to see what your machine is doing: a built-in web server to monitor and control from any browser, and free EasySCADA , a PC-based SCADA/HMI tool similar to commercial SCADA software, for building full visualization screens. For system integration, xLogic speaks Modbus, MQTT and BACnet over wired Ethernet , connecting directly to SCADA, BMS and IIoT platforms.

Who uses xLogic:

• Equipment OEMs — packaging, food processing, woodworking and plastic auxiliary machines.
• HVAC & building automation contractors — fan coil units, ventilation, booster pumps, lighting control.
• Agriculture & greenhouse integrators — irrigation, ventilation, shading and climate control.
• Water & pump control — mini sewage equipment, irrigation pump stations, pool circulation.

All xLogic products comply with RoHS and carry CE certification. Every controller ships with an 18-month warranty , free programming software and access to our application engineering team. Need a custom I/O layout or a pre-programmed logic template? We support OEM/ODM customization .
