1 Process DisplayRIA 250 Multifunctional 1 channel Display withuniversal input, loop power supply, alarm limits,and analog outputApplication Areas Plant and machine construction Control panels Laboratory fittings Temperature Display and monitoring Process Display and monitoring Process control Signal match and transformingAdvantages Multi functional:All normal measurement signals canbe directly connected (bipolar voltageand current, thermocouple, RTD) Display :Active numeric measured valuedisplay with bar graph Alarm:Flexible set point monitor with2 relay contacts Active:Adjustable current or voltage analogoutput Power:Integrated loop power supply forconnected sensors Communicative:RS 232 interface for set-upconfiguration and measured valueoutputTechnical InformationTI 060R/24/aeThe Power of Know How2 FunctionsThe presettable universal input enablesdirect connection of various sensors,including current, voltage, RTD andthermocouples.

2 Using the built-in looppower supply, the RIA 250 can power aconnected sensor, and then it canevaluate its signal to the RIA 250. Twopresettable alarm set points monitor themeasured value for any deviation fromthe preset adjustable analog output offers aninstrument from which a matched signalfor further analysis equipment can beobtained. Simple configuration isavailable directly at the RIA 250 via a control is simplified with theRIA 250 which can transmit power to atransmitter, receive and indicate auniversal input, and transmit an analogoutput signal (optional) or communicatevia withReadWin 2000 PCSoftwareThe RIA 250 can be set up extremelyeasily using the built-in RS 232 serialinterface and the Endress+HauserReadWin 2000 PC software. Safe andsecure set-up is made possible via on-line help text.
