The Mitsubishi PLC Module FX1N-40MT-D / FX1N-40MR-D delivers uncompromising control for mid-scale industrial systems, combining a compact footprint with advanced processing capabilities. Designed for cyclic stored program operation, it executes basic instructions in just 0.55 to 0.7 µs and applied instructions in 1.65 µs to several 100 ms, ensuring real-time responsiveness. With up to 128 I/O points, 8K steps of memory, and support for relay symbolic and step ladder languages, this module is ideal for applications requiring precise timing, high-speed counting, and extensive data handling.
