Page 2: Owner Information
This includes checking the transmitter frequency and deviation periodically, using appropriate methods. Your RITRON dealer can help you obtain a FCC license. To get a FCC license for VHF or UHF frequencies, submit FCC application Form 600. - Page 3 RITRON DATAFLOW RTU and MODBUS radio communications equipment replaces these methods. This manual is intended to provide information needed for the installation and operation of RITRON DATAFLOW RTU systems. The intended readers are people familiar with industrial instrumentation. A basic understanding of radio communications is helpful.
- Page 4 FCC ID: RTU-150 - AIERIT04-150 RTU-450 - AIERIT04-450 Emission designator: 10K8FID Digital Inputs: Maximum of 6 LOW: programmable from 0 to 5 V HIGH: programmable from 0 to 5 V Digital Outputs: 2 isolated latching relays UL/CSA rating: 2.0A 30VDC .5A 110VDC .5A 125VAC Analog Inputs:...

- Page 6 paragraph to attach the mounting bracket to the case. Be sure the narrow portion of the keyhole is positioned towards the top (UHF antenna connector) of the DATAFLOW RTU. 10.1 The RTU power source is a user-provided external power supply meeting the following criteria: Between 10 VDC and 16 VDC with 12 VDC nominal;...
- Page 7 GROUND. The threshold level between HIGH and LOW is programmed with DATAFLOW RTU Programming Software. HIGH programmable V Programmable k ohm infinite ohm programmable V 0 ohm programmable k ohm ABSOLUTE LIMITS -2 V 13.1.1 You can invert the input state of a RTU unit, which will cause a DATAFLOW RTU reading a switch as HIGH to transmit the switch status as HIGH to another DATAFLOW RTU.
- Page 8 INPUT RANGE 0 mA 20 mA SOURCE IMPEDANCE (Ev-5)/.02 ohm ABSOLUTE LIMITS -8 mA 28 mA 15.2 All analog inputs are non-isolated. All analog measurements are referenced to GROUND. Take care when connecting the DATAFLOW RTU to external sensors. 15.3 The user can invert the input state of a DATAFLOW RTU if desired, which will cause a DATAFLOW RTU that reads an analog signal as full scale to transmit the signal status as a 0 scale to another DATAFLOW RTU.
- Page 9 over a RS-485 serial link. The following paragraphs describe how individual blocks of the control board operate. 17.1.1 +5V REGULATOR: IC101 is a DC-to-DC converter which changes the VUNREG input voltage to +5VDC. The +5VDC value is set by resistors R101, R102, and R103 with FB = 2.50V (pin 13). This IC also contains an output comparator used to monitor system +5VDC voltage.
- Page 10 17.2 See the applicable RITRON DTX manual for the RF board theory of operation. When using the DTX manual in support of the DATAFLOW RTU only the RF portion is valid. Disregard all references to the DTX control board.
