MMi203A – Operator interface and analog

Product Information

• Description

  

  The MMi203A gives your product a powerful electronic controller. Along with digital I/O, it has analog I/O and a built in user interface. The MMi203A is an extremely cost-effective alternative to conventional programmable logic controllers and opens the door to functionality and a level of support you could previously only dream about. It can be programmed in our controls-optimised, easy to learn proprietary SPLat language, or in C. We can also program it for you if required.

• Features

  The MMi203A includes all of these features as standard:

  • 8 x digital pins outputs with capacity up to 500mA at 24V, capable of switching inductive loads such as solenoids and relays.
  • 2 x analog inputs, each can be configured as either: Temperature (external thermistor), 0 – 20mA, 4 – 20mA, 0 – 10V, 0 – 5V.
  • 8 x digital inputs are rated for industrial NPN sensors up to 24V.
  • 2 x analogue 0 – 10V outputs.
  • 1 x RS485 port, may be used for long distance Xwire expansion bus.
  • 1 x RS232 serial port.
  • 1 x TTL Xwire port.
  • 5 x Front Panel push buttons.
  • 7 x Programmable Front Panel red LEDs, plus 1 x green Power LED.
  • 100 year Real Time Clock (on board supercap, or bring your own battery).
  • Optional 2 x 16 backlit character LCD with dimmable backlight.
  • Beeper for button confirmation and alerts.
  • I/O Expansion connector.
  • SPice connector.
  • Works with all our Xwire expansion boards.

• Special Function

  You also get the capacity to expand up to 40 inputs and 40 outputs in addition to accepting a wide range of special function interfaces like:

  • Internet connectivity
  • ultrasonic ranging
  • pH measurement
  • fluid level sensing
  • and more…

  The MMi203A is a drop in replacement for the MMi202. The connectors, board size and programming is identical. However the MMi203A has more memory and comes with a real time clock and RS485 port as standard, at no extra cost. Just like its predecessor, the MMi203A can be ordered in a few configurations. See below.
