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:

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.

This is the same backlit display we supply with the MMi203ADK216. It is supplied complete with a connection cable and mounting hardware.

Dimming the display can provide considerable extension of the 3000 hour rated lifetime of the LED backlight. Programming examples

' ); EmbedProduct( 10159, ' LCD 16x4

This large backlit display gives you more than twice the display capacity of our "standard" 2x16 LCD. It is supplied complete with a connection cable and mounting hardware.

Dimming the display can provide considerable extension of the 3000 hour rated lifetime of the LED backlight. Programming examples

Note that we do not at present have matching metal face plates or graphics overlays to go with the 4x20 display.
