Mitsubishi FX Series PLC Hardware Wiring and Soft Component Description

The Mitsubishi FX series PLC is a compact, integrated PLC developed by Mitsubishi, with a significant market presence in China. It includes several sub-series, such as FX1S, FX1N, FX1NC, FX2N, FX2NC, and FX3U, FX3UC, FX3G, etc.

Among them, FX1S, FX1N, and FX1NC belong to the first generation; FX2N and FX2NC are second-generation models; while FX3U, FX3UC, and FX3G are third-generation models. Currently, first and second-generation models are the most widely used in practical applications. However, the third-generation models, with their powerful performance and competitive pricing compared to second-generation models, have attracted an increasing number of users, gradually expanding their market share.

FXINC, FX2NC, and FX3UC are the modified versions of the first, second, and third-generation models of the Mitsubishi FX series, respectively. The main differences between modified models and standard models are:

Modified models are smaller in size, suitable for installation in confined spaces;
Modified models use plug-in connections for terminals, while standard models use terminal block connections;
The input power for modified models can only be 24VDC, while standard models can use either 24VDC or AC power.
