Specification

SEODescription

The Mitsubishi FX2N-128MR PLC, part of the MELSEC-FX2N series, is a compact and versatile automation controller featuring 64 digital inputs and 64 relay outputs (128 I/O total) through its integrated FX2N Relay Output Unit. Designed for mid-range applications, it supports direct connection of up to 8 expansion modules for enhanced I/O flexibility and integrates communication via RS-232/RS-485 interfaces using optional adapters. Operating within 100-240V AC and a temperature range of 0-55°C, this PLC excels in manufacturing, packaging, and machinery control systems. Its relay outputs are ideal for high-switching-frequency tasks, though they may wear faster than solid-state alternatives. While praised for reliability and modularity, limitations include slower processing speeds compared to newer models and lack of native Ethernet support. The FX2N-128MR remains popular for cost-effective industrial automation solutions requiring robust relay-driven control.
