Digital I/O expansion boards increase the number of I/O points. These boards connect to the controller via a plug-in cable. Several expansion boards can be daisy chained, up to a maximum of 32 outputs and 32 inputs (or 32 bidirectional I/O points). When you connect expansion boards the controller detects them automatically and the programming software adjusts itself. There is no software configuration required.
These boards are compatible with the CC18, MMi203A, MS121 and SL100 controllers

An NPN input is ‘ON’ when the input pin is connected to circuit common either by a switch (or piece of wire) or by an industrial NPN sensor.
All inputs on all SPLat controllers have inbuilt contact debounce of 8-16mS. That means in most cases you can just hook them up to a switch or sensor and not have to worry about contact bounce. There are also non-debounced input instructions and latched input modes that will capture an OFF to ON transition. It is also possible to read 8 inputs at a time across any 8 contiguous inputs.
