6.5 Connecting Analogue Wind Instruments

A relatively common type of digital water level instrument is one that provides two pulse outputs. One output generates a pulse for each increment and the other for each decrement in level. The iRIS maintains a record of these steps and therefore the relative level.

These instruments normally require a 12V supply and this is readily obtained from the iRIS. A supplementary 12V battery can be connected if desired. Typically, this type of instrument requires very little current, so the internal iRIS 320 battery will normally suffice.

The diagram below shows the required connects for such an installation. The incrementing output must be connected to DI1 and the decrementing output to DI2.
