Module IO<br />

<strong>2704</strong> Controller<br />

18. Chapter 18 Module IO<br />

18.1. WHAT IS MODULE IO?<br />

Additional analogue <strong>and</strong> digital IO is provided by the plug in IO modules. These modules<br />

can be fitted in any of five slots (see Section 2.4.2). The type <strong>and</strong> position of any modules<br />

fitted in the <strong>controller</strong> is shown in the order code printed on the label on the side of the<br />

<strong>controller</strong>. This can be checked against the order code in Appendix A of this manual.<br />

Modules are available as single channel, two channel or three channel IO as listed below<br />

Parameters for the above modules, such as input/output limits, filter times <strong>and</strong> scaling of the<br />

IO, can be adjusted in the Module IO pages. The procedures are very similar to those covered<br />

in Chapter 17 ‘STANDARD IO’.<br />
