Autonomous Smart IO Management

This RZN is smart and can AUTONOMOUSLY manage the IO pins itself. You can use a master controller or HMI device to control the IOs or setup the RZN to manage the IOs itself. The RZN has more IO management features than any other RTU in the industry. There are commands within the RZN to setup all these features to just run in a remote are with no network connection, if you want to have it just autonomously read inputs and manage outputs based upon the inputs and time and date.

Here is a list of the features. You can choose and setup an Feature ID and Threshold Value (TV). When a Feature measures something you want, it will Control State of an Output Pin (CSOP) as you want it to do. When it Controls the State and Output Pin (CSOP), it can turn on or off a switched DC output, switched AC output, a digital output state, or turn on or off an Open Drain output.

‘A’ Angle of the unit.                      If the physical angle (X, Y,  or Z) angle of the unit goes beyond the TV it will do the CSOP.

‘B’ Raw Input Binary Event           If a digital input (TTL, button…) got into a mode you choose (0 or 1, On or Off), then it will do the CSOP.

‘C’ 4-20mA Input Current              If a the input current on a 4-20mA input sensor goes beyond the TV it will do the CSOP.

‘D’ DC input or Battery               If a internal power voltage goes above or below the TV it will do the CSOP in the way you want.

‘P’ Pulse Ticking Event                 If a digital input (TTL, button…) pulsed on/off more times per second or minute that you want, it will do the CSOP in the way you want.

‘R’ Pulse Ticking Event                If a internal vibration sensor pulsed on/off more times per second or minute that you want, it will do the CSOP in the way you want.

‘T’ Product Temperature               If the RZN’s temperature sensor goes above or below the TV it will do the CSOP in the way you want.

‘#’ Internal Register Value             If the internal register value within the RZN voltage goes above or below the TV it will do the CSOP in the way you want.

Industrial use of the RAZN

Here is a list of Industries Raveon created the RAZN to work with, and help Autonomously keep it safe, and have them be able to wirelessly monitor and control over large areas.

Machine Health Monitoring 

Monitor critical assets all time, and get notified of problems. The RAZN remote monitoring product has protection capabilities to your assets to improve plant reliability.

Security Alarm System applications:  Remotely monitor doors and gates. Trigger alert lights, beepers, or send text messages, or all.

Oil and gas pipelines:  Automate the collection and transfer of your field data to your system, and Autonomously keep the system safe when bad events happen.

Pumping Stations, Tanks, Oil or Water levels:  Reduce unplanned downtime. RAZN keeps production running smoothly by monitoring tanks.
RAZN’s wireless monitoring solution makes it easy to remotely monitor multiple tank levels so that your process is not unexpectedly interrupted.
Autonomously keep the system safe when bad events happen.

Lighting control with remote access, local switches, and timers:  Each RAZN has up to 8 switched voltage outputs (SV) to turn valves, lights, or pumps on or off.
The Real Time Clock (RTC) in the RAZN can autonomously turn lights on/off as you want, and the Ethernet and Long-range Wireless data communication links enable you to
control lights over cities, states, or across the country. or around the world.

Remote Irrigation control with remote access, local switches, water monitors, and timers.  The analog input sensors can also remotely control the irrigation.

Weather Stations:  The RAZN can monitor air-speed, read Thermocouple Temperature Sensors, monitor light, and trigger remote control based on all sensor inputs.
The RAZN can text the weather information to remote computers or networks. And it can monitor and send weather alert messages as you need.

Supervising and monitoring alarm systems; You may not have heard an alarm, but RAZN can help monitor and remotely alert your buildings security.

Autonomous Data Acquisition:  RAZN connects to your network using smart wireless sensors for prevention measures and send you data, or Autonomously control.

Vending Machines security protection: The RTC, input sensors, vibration sensors, and many others can monitor your machine to protect it, and notify you remotely.

Monitoring Buildings and Real Estate: The RTC, input sensors, vibration sensors, and many others can monitor your buildings to protect it, and notify you remotely.

River Monitoring and Flood Control:  The RAZN telemetry controller and monitor and you can remotely read river and flood information.
The RAZN can also autonomously control things and alert you related to water levels, flood, and so many sensors.

Automatic monitoring systems: The RAZN is the best automatic and autonomous monitoring SCADA PLC and RTU.
This modern smart technology, and Raveon’s data modems, makes this RAZN a great price, for reliable remote monitoring. And Controlling.

Traffic monitoring and traffic control: Any traffic sensors can be monitored by the RAZN. The smart CPU in it does the math you need, and you can monitor it.
The RAZN can also control what you want to control communicating to the RAZN, and Autonomously the RAZN can safely control traffic as you want, by it self.

Temperatures and water leakage applications; The ultra-high resolution analog input can monitor any temperature sensors,  and Thermocouples, and water detectors.
You can remotely read these sensors on the RAZN, and the RAZN can send the information to you, or Autonomously control what you want based on temperature and/or leakage.

Save Energy, street light control:  Lights can efficiently be Autonomously controlled the way you want with a RAZN. No cell fees, no people have to work hard to monitor.

Transformer stations and Valve Control: Monitor AC voltage, AC current, temperature, and enclosure status.  The RAZN can report to you, and you can read if you want.

Base Transceiver Monitoring:  You wireless base stations and towers, or cellular towers and systems, can be monitored with RAZN terminal inputs, and autonomously do what you want.
And if the system fails, the RZN can wirelessly still work and remotely send you information about the issue that cause a failure.

Fire detection:  This was a high priority of the RAZN concept.
The RAZN can monitor AC power cables to see if they break, and it can detect fire, and send an alert over 1-50 miles, even longer with an additional Raveon repeater.

Manage wind farms:   To save wire cost, and labor, the RAZN can monitor and measure whatever you want over 100 square miles, to make sure your windfarm is working as expected.

Methods to Control the Switched Voltage Outputs

The RZN makes remote automation and monitoring of your complex processes robust and cohesive by connecting across a variety of communication methods and data protocols.
