Every CI 45 has at least one universal input, one universal output and a relay. Optionally, the transmitter can be fitted with an additional relay, with a second universal input and counter or frequency input. Optionally, the voltage output can also be used as frequency output. Galvanic isolation is provided between inputs and outputs as well as from the supply voltage and the communication interfaces. Mounting The compact CI 45 is clipped onto a top-hat DIN rail, and can also be unmounted very simply. All connections are of the plug-in type, so that a transmitter can be replaced very quickly without disturbing the wiring. Display and operation The two-line LC display permits simultaneous indication of the measured value and all of the unit's operating functions. Moreover, a LED and 4 other display elements give a reliable indication of operating status, operating mode, and error messages. The user-configurable engineering unit of the measured value can be included in the display. By means of the extended Operating Level, it is possible to show any signal or parameter in the 2nd display line. Interfaces and Engineering Tools The transmitter settings are also configurable by means of an Engineering Tool. Via the BlueControl® software, including the transmitter simulation and especially the convenient connection via the BluePort® front interface, the

The engineering unit for the measured value can either be selected from a predefined list of standard units, or it can be defined by the user (BlueControl®). The unit appears in the second line of the display. Display of engineering units The transmitter contains a 1st-order mathematical filter with adjustable time constant and bandwidth. The bandwidth is the adjustable tolerance range within which the filter is active above and below the process value. Measurement value changes in excess of the adjusted bandwidth are not filtered.
