Transcont CR

• Compact design, only 22,5 mm wide
• Clips onto top-hat DIN rail
• Plug-in screw terminals or
• spring-clamp connectors
• Dual-line LC display with additional display elements
• Process values always in view
• Convenient 3-key operation
• Direct communication between mounted transmitters, fieldbus connections via bus coupler
• Up to two universal inputs with high signal resolution (>15 bits)
• Universal output with high resolution (14 bits) as combined voltage/ current output
• One or two relay outputs combined counter or frequency input, frequency output
• Quick response; only 100 ms cycle time, i.e. also suitable for fast signals
• Customer-specific linearization
• Measurement value correction (offset or 2-point)
• Min/max indicator (‘slave pointer’)
• Logical linking of digital outputs, e.g. for common alarms

Function description

Transcont CR transmitters are designedto give precise and cost-effectivesignal detection and processing tasks. Every CI 45 has at least one universalinput, one universal output and a relay.Optionally, the transmitter can be fittedwith an additional relay, with a seconduniversal input and counter orfrequency input. Optionally, the voltageoutput can also be used as frequencyoutput.
Galvanic isolation is provided betweeninputs and outputs as well as from thesupply voltage and the communicationinterfaces.

MountingThe compact CI 45 is clipped onto atop-hat DIN rail, and can also be unmountedvery simply.
All connections are of the plug-in type,so that a transmitter can be replacedvery quickly without disturbing the wiring.Display and operationThe two-line LC display permits simultaneousindication of the measured valueand all of the unit’s operatingfunctions.Moreover, a LED and 4 other displayelements give a reliable indication ofoperating status, operating mode, anderror messages.The user-configurable engineering unitof the measured value can be includedin the display. By means of the extendedOperating Level, it is possible toshow any signal or parameter in the2nd display line. Interfaces and Engineering ToolsThe transmitter settings are also configurableby means of an EngineeringTool.Via the BlueControl® software, includingthe transmitter simulation andespecially the convenient connectionvia the BluePort® front interface, the Transcont CR Universal transmitter Compact design Display operating functions Communication featuresHigh resolutionFast cycle timesTwo universal inputs&universal output
