Remote Autonomous Zone Node RTU/PLC

The RAZN is an automated peripheral to remotely monitor sensors and can also remotely control your things.
Use and and RTU or PLC, and it can also autonomously do what needs to be done. This makes your system safer because it will do things if the controller or network fails.

Long Range Wireless options are: narrow UHF or VHF channels, or license-free ISM band. Internal wireless modems within the RAZN can mesh RAZNs together.

To meet your needs, Raveon created an easy to use automated peripheral with wireless data links built into it. SCADA and Telemetry requirements are good to use the RAZN.

RAZN RV-N55-8 Product Features


We offer more features, great performance, and a reliable product at an exceptional price.

Remotely monitor our output TTL digital signals. Up to 16 General Purpose IO terminals are on this.
4 of the terminal can be used read voltage or sensors. These 4 can be setup to read 4-30mA current sensors.
When 4-20mA is enabled, there is an internal 120 ohm resistor to draw the current.
One terminal has a relay driver output on it to control a relay, light, or whatever you want to turn on with switched ground output.


  • 16 TTL (3.3V) compatible GPIOs available. 5.0V available.
  • 4 Analog input channels (Multiplexed with GPIOs)
  • 12 Bit Analog input resolution
  • GPIOs can be individually configured as input or output.
  • Can be controlled by serial console commands, MODBUS, or custom applications.
  • All IOs available on easy to access terminals blocks using terminals with screw-down interfaces.

Voltage Sensors

RAZN has  4l voltage sensor in it used to measure voltage with 12 bit resolution, and can also measure current and 4-20mA.

Flexible TTL IOs   (FIO)

The FIO pins can be setup as TTL digital input or outputs.  16 of the terminals can be used for FIO.

Robust, Reliable and Protected

The IO pins have great electrostatic discharge (ESD) and over-voltage protection. DC power input is reverse and over-voltage protected.
Internal smart CPU has watchdog timer, data stored in EEPROM, and battery powered clock.
Long-range communications uses wireless instead long copper that will fail.

High Performance Interfaces

Ethernet, RS-485, USB, and many RF options.  RAZN wireless links are super long-range communication. 1/2W to 5W UHF, VHF; 50mW-1W ISM LoRa. Verify operation and quality of connection in the field from 1 to 50 miles. The RAZN can also communicate with Raveon’s data radio modems (RV-M6, RV-M8, RV-M7, RV-M9 …)

Real Time Clock (RTC)

The battery backed up internal RTC is accurate and keeps track of all time, milliseconds, seconds, minutes, hours, days, weeks, months, and years.
It can be used to trigger events, and also time events and stop them when the time is over.
Timer events can turn things on or off based upon any time status you prefer.

A Myriad of Ways to Use This

Point-to-Point: The two RAZNs can work together by themselves and control what you want in isolated areas.
You can use 2-200 of these RAZNs to do what you need to control in isolated areas.
We offer more features, good performance, and a reliable product at an exceptional price.

Master Control

Use a remote master controller PC, GUI, IoT server, or MODBUS master to communicate with the RAZN and control your things in isolated areas.
Some RAZNs have sensor inputs, so sensors placed in the root zone of the plants to remotely control irrigation.

Timers and Real Time Clocks

All RAZNs have a Timer Operations Actions Alerts (TOAA) feature to use its timers to do what you want and when you want to have it done.
Button inputs can trigger timers to turn remote things on or off for specific time periods.
This automated peripheral RAZN is patented with TOAA and a myriad of features. This is a complete solution to remotely control things

Graphical User Interface (GUI).

A graphical display panel  can be connected to the RAZN to display the status of the GPIO terminals, or the status of terminals at a .

The RAZN can display remote status or control remote terminals, and a GUI on the master can also do that in a nice graphical way.

This is Made in America.

Raveon designed this in California, and all RAZN technology, and the RF radios in the RAZN, are made here in America.

List how How to Setup the RAZN to remotely control an an automated peripheral

RV-N55-3B with MODEM

RV-N55-3B has 8 switched power outputs to remotely control things.
Your Controller connects to a radio modem to communicate to a RAZN in a remote area.

The RV-M22 is license free ISM band radio modem that is perfect for remotely controlling things using.

RV-N55-3B & RV-N55-3C

RV-N55-3B can be controlled by a RV-N55C RAZN with 1-8 buttons input. Push a button to turn remote things on /off. And Autonomous logic and timers work in both RAZNs

The RV-N55-3B terminal ports are turned on/off by the 3C. the Buttons on the 3C can control the 3B terminals to turn on off things like lights, valves, pumps, or whatever.
The 3B has a timer in it to automatically do what you want, and the buttons can be setup to turn on a terminal port of the 3B of xx amount of seconds, minutes or hours.

RV-N55-3E & RV-N55-3C

The RV-N55-3E be connect to a PC, tablet, or server to control the RV-N55-3B terminal ports in a remote area.

The RV-N55-3E has an Ethernet interface on it to connect to your controller. Or it can connect to your network. The RV-N55-3E can work with SCADA software that use MODBUS messages.
The Buttons on the 3E can also be used to turn on/off the remote peripheral 3B terminal ports.
