Micro PLC - Small PLC Options From Unitronics

A cheap PLC used to mean limited control capability and next to no HMI - but not any more. Now you can replace that "smart relay" with a real micro PLC for the same low price. Programmable controllers from the Unitronics PLC range offer exceptional value for money, combining integrated HMI with powerful control and communications capabilities.

These mini PLCs are ideal for low complexity applications requiring a small PLC yet with rich control and HMI features. Unlike programmable relays or other simple PLCs on the market, these micro PLCs have high level PID algorithms and accept temperature sensors without the need for in line transmitters.

The M90/91 is an innovative micro PLC with a built in operating panel. The operating panel comprises a one line (M90) or two line (M91) LCD text display (16 characters per line) and a keypad.

Despite being a small PLC, there is a choice of onboard I/O configurations including direct temperature inputs and weight measurement inputs.

As with other programmable controllers in the Unitronics PLC range, expansion is also possible using remote I/O expansion modules.

As well as supporting up to 80 user-designed screens, this low cost PLC supports 15 different languages and allows troubleshooting directly via the HMI panel.

  • Ladder logic software (free of charge)
  • Direct temperature inputs
  • 4 loops of auto-tuning PID
  • SMS messaging via GSM
  • Remote access capability
  • RS232/485 port built in
  • MODBUS and CANbus possible
  • Shaft encoder inputs and PWM outputs
  • Supports over 15 languages and 20 graphic symbols
  • Scroll between pre-programmed recipes/menus
  • Built in I/O and expansion possible
  • Print utilities
  • Up to 80 user-designed screens
