Mitsubishi Alpha 2

Alpha 2: Advanced Tiny Giants

Alpha 2 Base Unit

The Alpha 2 (Alpha XL), an upgrade on Mitsubishi's Alpha controller, fills the gap between traditional relays and timers and a full-fledged PLC, offering functionality, reliability, and flexibility without the worry of increased overhead cost. Aimed at very low end applications where a traditional PLC is not required, the Alpha 2 offers some unique capabilities, such as high current relays, built-in analog inputs, built-in HMI, real time clock, AS-i networking, and an innovative graphical programming system.

The Alpha 2 is the perfect maintenance product, yet can adequately control a new process from the start. The Alpha 2 can process up to 200 function blocks in a single program, and every single function (timers, counters, analog signal processing, calendar, clock etc.) can be used as many times as you need in all your programs.

The Alpha 2 (Alpha XL) brings the benefits of the Alpha closer to the functionality of a Micro PLC. The Alpha 2 has fifteen new function blocks including mathematical operations, PWM, 1KHz high speed counter and SMS text messaging, along with a wide operating temperature (-25 to 55°C). The large back lit screen features display options including bar graphs and scrolling text. Optional extension units can increase the I/O by four points of digital I/O.
