FX3GC-32MT/DSS - Mitsubishi Programmable Controllers Melsec

The FX3GC-32MT/DSS by Mitsubishi is a high-efficiency programmable logic controller (PLC) built for applications that require performance and compactness. Operating at 24V DC with just 8W of power consumption, it includes 32K EEPROM program memory and executes both LD and MOV instructions at a fast 210–500 nanoseconds. This makes it suitable for fast-response environments like machine tools, bottling plants, or process skids.

Equipped with 16 digital inputs and 16 transistor outputs in source logic, the FX3GC-32MT/DSS enables reliable signal handling and output control. The unit supports up to 128 local I/O points and 258 local + remote I/O points, and its expansion-ready architecture ensures that it can scale with growing system needs. The RS-485 interface allows connection to serial devices, HMIs, and energy meters, enhancing field-level communication. With IP10-rated protection, the controller ensures safety in enclosed panels, while its compliance with UL/cUL, UKCA, and CE standards reflects global acceptance.

Its minimal footprint—just 34 mm wide and 0.2 kg in weight—makes it ideal for panel builders and OEMs targeting compact machine control solutions. The Mitsubishi FX3GC-32MT/DSS PLC performs reliably up to 55°C, with optional buffer battery support for memory retention. With decades of industrial expertise, Mitsubishi ensures long-term supply chain reliability and technical support. Visit the official Mitsubishi product page for more details and full documentation.

The FX3GC-32MT/DSS is especially suited for automation scenarios where space is limited but control complexity is non-negotiable. For example, in compact control panels for food packaging or labeling machines, this PLC delivers real-time execution of input/output signals with fast cycle times and low latency.

In a typical use case, 16 inputs might monitor photoelectric sensors, limit switches, or float sensors, while 16 outputs drive solenoids, small motors, or indicators. The transistor outputs ensure smooth operation of fast-switching devices, while RS-485 connectivity allows the unit to communicate with drives or temperature controllers without additional converters. This makes the FX3GC ideal for modular automation tasks that require repeatable performance and centralized diagnostics.

Thanks to its expandable I/O support and high-speed instruction processing, engineers can deploy this PLC in applications like batch dosing systems, small conveyors, or test benches. Whether you’re building a new control system or replacing bulky relay logic, the Mitsubishi FX3GC-32MT/DSS provides a cost-effective, future-ready solution for smart industrial control.
