The Mitsubishi AL2 Series Micro Programmable Logic Controller combines the CPU, power supply, and I/O units into a single compact module, enabling a complete basic control system without additional modules. This simplifies configuration and installation while saving space.
It includes 10 flexible relay outputs, each independently isolated, capable of driving AC or DC loads such as contactor coils, solenoid valves, and indicator lights, with a load capacity of 2A @ 250V AC or 2A @ 30V DC. In addition, the 14 digital inputs support DC 24V signals and use a sinking input method, making them compatible with common devices like pushbuttons, switches, and proximity sensors. Removable screw-clamp terminals ensure convenient wiring.
Programming is simple with Mitsubishi’s ALPHA2 tool and a dedicated programming cable. Moreover, the built-in RUN/STOP switch and status LEDs (POWER, RUN, ERROR, and I/O) help with operation and troubleshooting. Despite its small size, the PLC provides essential functions such as timers, counters, auxiliary relays, and a high-speed counter on select inputs, supporting most basic sequential control and counting tasks.
Finally, as an entry-level PLC, it offers competitive pricing while maintaining Mitsubishi’s reliability, making it ideal for compact, cost-sensitive automation projects.
