Mitsubishi AX20 Programmable Logic Controller CPU Unit for MELSEC-F FX3S

The Mitsubishi AX20 (AX20) is an entry-level programmable logic controller central processing unit designed for the Mitsubishi MELSEC-F FX3S series. Delivering compact and reliable automation control, this unit features 10 integrated input and output channels, making it suitable for standalone machinery, small automation setups, and industrial control equipment. It is equipped with six digital inputs operating at 24 V DC with sink or source logic selection, alongside four digital outputs rated for 5 to 30 V DC with positive source logic, a 500 mA load current capacity, and a fast 0.2 ms response time. Equipped with an internal EEPROM program memory capable of storing up to 4,000 steps, the controller operates on a 24 V DC power supply. Functionally equivalent to the FX3S-10MT/DSS model, it executes sequence control and switching tasks in manufacturing machinery, packaging systems, and assembly lines. Its integrated architecture streamlines wiring and offers dependable operation for machine retrofits and factory automation tasks.
