Alpha fills the gap between traditional relays and timers and a PLC. Offering functionality, reliability and flexibility but without the worry of cost of overheads.

Alpha is the perfect maintenance product, and yet can adequately control a new process from the start. The Alpha 2 (Alpha XL) 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.

What can you expect from the ALPHA series?

The integrated products of the ALPHA family replace many of the discrete components used in conventional systems, opening up a whole new range of possibilities for economical solutions.

  • Greenhouses and agricultural machinery
  • Pump controllers
  • Handling systems
  • Door, gate and window blind controllers
  • Special-purpose vehicles
  • Heating, air-conditioning and ventilation
  • Lighting systems
  • Alarm and security systems
  • Outdoor applications

All-in-one power supply, CPU, and I/O main unit. Built-in features include display, analog inputs, counters, timers and GSM functionality.
