The Mitsubishi MELSEC-L L26CPU-CM and L26CPU-BT-CM are high-end CPU modules from the acclaimed MELSEC-L series, designed for demanding industrial automation applications. These units deliver exceptional processing power with a program capacity of 260K steps and a basic operation speed (LD instruction) of approximately 9.5 ns. The L26CPU-CM features a standard Ethernet port for open network communication, while the L26CPU-BT-CM incorporates a built-in CC-Link IE Field network interface for high-speed deterministic control. Both modules support up to 4096 I/O points, making them ideal for mid-to-large scale systems requiring precise and reliable control. Below are the detailed technical specifications.
