4DIX Digital Input Expander Module

4DIX Digital Input Expander Modules allows 4 volt free inputs to be monitored by a single analogue input channel. The resultant analogue value can be decoded by the A to D Function Module in an IQ controller to produce internal digital status bits for alarm monitoring or other status input applications. Wiring is facilitated by rising cage clamp type terminals, and a supply loop terminal aids wiring to additional modules. The SET 4DIX strategy blocks apply to IQ1, IQ2, IQ3/4, and IQeco and set up both sensor scaling and strategy modules. SET Strategy Library Path = Standard Block/Trend Products/ Input Output Modules/4Dix 4 Digit Expander Module/P01 - 4Dix Expander Module. Faster operation of the inputs on post IQ2 controllers (IQeco, IQ3, IQ4) requires a more complex strategy. The input value requires to be steady for 1 second before being decoded. This removes unwanted signals being processed when the 4DIX transitions between states
