DataFlow RTU : Radio Telemetry Systems& Discontinued
DataFlow RTURadio TelemetrySystemsMADE INUSA1546 Basic UnitDataFlow radio telemetry transceiver shown with antennaThe DataFlow RTU is a completewireless telemetry system designedto deliver industrial instrumentationsignals from a source to otherinstruments via radio frequencycommunications. The DataFlow RTUallows you to access industrialmeasuring devices in remotelocations without running wires,installing microwave links or leasingtelephone lines.The DataFlow RTU is a radiotelemetry system that operates oneither UHF-FM (450 to 470 MHzwith a transmitter power of 2 Wattsor 5 Watts) or VHF-FM (150 to165 MHz, 136 to 151 MHz and 160to 174 MHz with a transmitter powerof 5 Watts). An RTU systemoperating in the UHF-FM band at 2Watts with directional antennas and50-foot towers has an effectiverange of 20 to 25 miles over levelterrain. Changes in the frequency ofoperation, transmitter power, terrainand antenna structure will affect therange of the link.All DataFlow RTU systems requireC-93FCC licensing. Call OMEGA forinformation on obtaining a license.InterconnectsThe DataFlow RTU provides awater-tight aluminum enclosure withtwo bulkhead circular connectors andone antenna port. Each DataFlow RTUcomes equipped with a 6' power/serial cable, which provides aconnection from the RTU to 12 Vdcpower and to an RS-485 serial port.It also comes with a 6' Input/Outputcable for connecting externalinstrumentation.

Thisprogrammable configuration can bechanged by any IBM PC orcompatible computer, using theDataFlow RTU’s ProgrammingSoftware and Programming Cable.PowerThe DataFlow RTU can be poweredby a dc voltage source that meetsthe following criteria: between10 Vdc and 16 Vdc with 12 Vdcnominal, less than 1 V peak-to-peakof ripple, 1.5 A with the transmitterin low power setting and 2.5 A withthe transmitter in high power setting.I/O MappingYou can purchase the DataFlow RTUwith an eight-cell internal batteryholder. With this option, internalAA batteries are used as the powersource for the low power setting.An ac to dc adaptor can also bepurchased if battery power is notpreferred, or if dc power is notreadily available at the installationsite. It can provide power for the1.5 A low power setting only.RS-485 Serial LinkThis link permits the user to changethe software configuration, andallows the RTU to be controlled byan external computer or PLC, viaRTU MODBUS Protocol. The baudrate of this link is programmablebetween 1200, 2400, 4800, and9600 BPS.C-94I/O mapping is the connection ofone DataFlow RTU input to anotherDataFlow RTU output via radiocommunication. The currentmapping scheme allows any input ofany DataFlow RTU to be sent to anyoutput of any other DataFlow RTU.Digital I/OThe DataFlow RTU provides 6digital inputs and two digital outputs.These outputs are two dry-contactclosure latching relays. They areeither OPEN or CLOSED and arecontrolled by the DataFlow RTUsoftware. You can invert the inputstate of an RTU unit, which willcause a DataFlow RTU which isreading a switch setting as “HIGH”to transmit the switch status as

The initial conditionforces the relays to a desired stateat power-on of the device. Thefail-safe condition forces the relaysto a desired state if an RF data linkproblem is detected. If a digitaloutput is used for a warningindicator, it is not available to bemapped to the corresponding digitalinput of the other unit. This meansthat if a digital output is used for awarning indicator, only one digitalsignal can be sent to that DataFlowRTU.Because the relays are latching,they retain the state they are in ifpower to the DataFlow RTU is lost;they will not go to the OPEN stateduring a power outage.Analog InputsUp to six analog inputs areprovided. These inputs can beof two types: 0 to 5 Vdc voltageor 0 to 20 mA current loop. Theseinputs are used to digitize theanalog signal and transmit it toanother DataFlow RTU.All analog inputs are non-isolated.The user can invert the input stateof a DataFlow RTU if desired, whichwill cause a DataFlow RTU thatreads an analog signal as full scaleto transmit the signal status at 0scale to another DataFlow RTU.This inversion allows a positivetransfer function signal to control anegative transfer function signalwithout external circuitry. Sensorexcitation voltage can be supplied bythe DataFlow RTU using the PowerOut pin. For this configuration, makesure to not exceed the maximumcurrent drive of the pin, andascertain that your sensor willoperate on a supply voltage ofVsupply-5 Volts.Analog OutputsTwo analog outputs are provided.These outputs can be configured aseither a 0 to 5 Vdc voltage or a 0 to20 mA current output. The analogoutputs can be programmed to haveboth initial and fail-safe conditions.The initial condition forces theoutput to a desired state at power-onof the device. The fail-safe conditionforces the output to a desired stateif an RF data link problem isdetected. Meter excitation voltagecan be provided by the DataFlowRTU using the Power Out pin. If thePower Out pin is used as theexcitation supply, make sure thatthe maximum current drive of thepin is not exceeded and that yourindicator will operate on a supplyvoltage of Vsupply-5.5 Volts.C-95General SpecificationsFCC ID: RTU-150 - AIERIT04-150;RTU-450 - AIERIT04-450Emission Designator: 10K8FIDDigital Inputs: maximum of 6, 0-5 VDigital Outputs: 2 isolated latchingrelays UL/CSA rating: 2 A @ 30 Vdc;0.5 A @110 Vdc; 0.5 A @ 125 VacAnalog Inputs: maximum of 6Voltage Mode Range: 0-5 VdcCurrent Loop Mode Range: 0-20 mAResolution: 8 bitsAnalog Outputs: maximum of 2Analog Voltage Mode Range: 0-5 VdcCurrent Loop Mode Range: 0-20 mAResolution: 8 bitsRadio Communications: FSK,1200 BPS, proprietary ManchesterEncoded data formatSerial Communications: RS-485;1200, 2400, 4800, or 9600 BPS;RTU MODBUS for programmingand external controlPower Requirements: 10-16 Vdc,300 µA sleep, 100 mA receive1.5 A low power transmit, 2.5 A highpower transmitHousing: diecast aluminum,watertightDimensions(L x W x H):4.5 x 3.5 x 2.2" (114 x 89 x 56 mm)Weight: 1.4 lb (.63 kg)Operating Temperature: -30 to 60 C(-22 to 140 F)Storage Temperature: -40 to 80 C(-40 to 176 F)
