The Wecon LX3V Series is a compact, cost-effective programmable logic controller (PLC) that offers an attractive combination of performance, familiarity and value for machine builders and system integrators. Notably, its instruction set is compatible with the widely used Mitsubishi FX series, allowing engineers experienced with that platform to develop and migrate applications quickly and confidently. This compatibility, paired with fast processing, practical motion features and flexible communications, makes the LX3V a popular choice for OEM machinery and general automation where reliable control is needed at a competitive price.
A key advantage of the LX3V is its Mitsubishi FX-compatible programming.
Engineers can leverage existing knowledge, programming habits and even adapted application logic, dramatically reducing the learning curve and accelerating development.
This familiarity lowers engineering risk and cost for teams transitioning to or standardising on Wecon, while still delivering the dependable logic control that machines require.
The controller supports a comprehensive instruction set covering logic, timing, counting and sequencing, enabling it to handle a broad range of discrete and simple analogue control tasks.
Performance is well matched to compact automation.
The LX3V provides fast scan times that ensure responsive machine behaviour, along with high-speed counting and pulse output capabilities that support basic positioning and motion-related tasks.
These features allow the controller to manage indexing, cut-to-length, simple synchronised movement and frequency measurement, broadening its applicability to machines that need light motion control without a dedicated motion platform.
The result is smooth, reliable operation across many common machine functions.
Communications flexibility ensures straightforward integration into control systems.
The LX3V offers RS-422 and RS-485 communication with Modbus support, enabling it to connect easily to HMIs, drives, servos, sensors, instruments and supervisory systems.
This native connectivity simplifies data exchange and control coordination across the machine, reduces wiring and engineering effort, and allows the controller to participate in larger networked architectures.
Combined with Wecon's own HMIs and drives, the LX3V supports cohesive, single-brand machine solutions that streamline commissioning and interoperation.
The series is available with output options to match different load types, including relay and transistor variants (model dependent), along with a range of I/O point counts. Relay outputs suit contactors and slower loads, while transistor outputs support high-speed switching and the pulse-train signals needed for positioning. This flexibility, together with the controller's compact dimensions and DIN-rail mounting, makes it easy to integrate into tight enclosures and to tailor the controller precisely to each machine's electrical and motion requirements, supporting standardisation across a product line.
Engineering is supported by Wecon's PLC programming software, which provides an efficient, familiar environment for developing, simulating, downloading and maintaining control programs. The FX-compatible approach and Wecon's growing ecosystem and support resources help teams develop machines quickly and maintain them confidently over their service life, while the controller's reliability and compact design contribute to a low total cost of ownership.
For buyers, the LX3V offers an economical, low-risk path to capable automation, with the advantage of FX-compatible programming and seamless integration with Wecon HMIs and drives. This enables organisations to build complete, coordinated machine solutions while keeping costs competitive and leveraging existing engineering expertise.
