MMi203A Electronic controller with operator interface

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.

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.
