Isolated IOs in the Remote Autonomous Zone Node RTU/PLC

The RV-N55-9 RAZN is an RTU automated peripheral with many Isolated Inputs and Outputs.

Many General Purpose IO (GPIO) features are configurable, and this one device has many IO features.  RV-N55-9C has all isolated GPIOs as Switched Voltage SV outputs.
The version RV-N55-9D has the Terminal A SV outputs configured to control Solenoids. 3-Pin solenoids can be controlled by the RV-N55-9D version.

This RV-N55-9 RAZN has 14 IO features, and 8 of them are totally Isolated from the RAZN and from each other.
SCADA systems can link via wireless long-range, or Ethernet, or RS-232 so SCADA links will work reliably with the RAZN.
Technical information about the IO terminal architecture is shown on the Terminal Information page..

Communicate with Raveon’s data radio modem inside this RAZN. TCP/IP Ethernet ports are available, and RS-485 serial ports are on all RAZNs.

Drive a Solenoid with the switched voltage output drivers, and Autonomous duration limitations in the RAZN will pulse the Solenoid correct.
For a 2-Pin solenoid driver, the RV-N55-5 is setup to do that.

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

To meet your needs, Raveon created this easy to use RAZN which can be a RTU or PLC, with wireless data links built into it, and many great IO features.
And it has more Programmable Logic Features within it (for Autonomous operation) than any other RTU or PLC in the world.

Use this as an RTU or PLC. You can control it to do what ever you want it to do, 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.

High Isolation Inputs And Outputs

RAZN uses a 12 bit differential voltage sensor (the best in the world ADC) to measure voltage with 1k resolution. It can also measure current and 4-20mA current sensors.
Use this analog interface for  Sensors to Monitor .  Detailed information about the sensor inputs is on the Terminal Information page..
The RAZN can be re-configured to reliably and accurately monitor sensors and the Autonomous features can monitor high resolution sensors and autonomously control things the way you want.
AN236_Thermotypes (pdf)  Explains how to use Thermocouple Sensors. They can be monitored many miles away with RAZN wireless technology, and can Autonomously control things you want to control.
And you can connect a RAZN to your network to monitor Thermocouple Sensors, or look at a Display or GUI and see the temperature, or have the RAZN beep or flash a light base on Temperature.

RV-N55-9C   IO Interface Information

RV-N55-9 The RV-N55-9 RAZN can be a RTU connected to a PLC using a Data Radio modem to communicate over many miles.

Status Recorder and Data Logging

The RAZN can be setup to record the status of inputs, outputs, communications, or whatever you want.
The large EEPROM inside the RAZN can store the data information you want, and no battery is required. Read it remotely via wireless link, or use the Ethernet interface.
Any register that monitors inputs, outputs, status, communications, timing, events, or whatever can be logged in to real later.

Automated Peripheral

RAZN can remotely control and monitor lights, pumps, valves, alarms, doors, AC power, DC power, or almost whatever you would like to monitor or control.
Monitor and Control using MODBUS messages. Communicate using  wires, Ethernet, or long-range wireless links. All methods are available.
And you can configure the RAZN to Autonomously monitor sensors and do what every you want Autonomously to keep your system safe.

Control Latching Solenoid

The RV-N55-9D can controls a 3-pin latching Solenoid, well managed by the RAZN.   SCADA controllers can do all the controls.
The RAZN can be setup to properly pulse the SD1 and SD2 pins to manage to Latching Solenoid. By default, they pulse at 150mS to turn it On or OFF.

The RV-N55-5 can controls 2-pin latching Solenoids.   SCADA controllers can do all the controls, or the RAZN can.

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 for a SCADA link.  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-M50 …).  Use these interface for the Sensors to Monitor.

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 These

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.
RAZNs have Many different IO terminal features. Technology insight into IO terminals is on the Terminal Information page..

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

Raveon has many Complete Solutions to automatically Monitor and Control things.

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

RV-N55-9C  Has many isolated IO terminal features. And it has Switched Voltage (SV)
outputs to control solenoids, relays, lights, pumps, valves, or whatever.
Many isolated digital inputs, outputs, voltage monitoring inputs, and isolated 4-20mA sensor inputs.

This version has 4 isolated  SV Switched Voltage outputs.
Your system can pulse latching solenoids with this.

The other RV-N55-9D version has latching solenoid driver outputs to drive 3-pin latching solenoids instead of SV.
And a Myriad of Isolated IO features: IAI, LI, OIDI, OIDO!

Here is the architecture of 3-pin latching solenoids:

RV-N55-9D  Has many isolated IO terminal features. And it has two (2)  Latching Solenoid Drivers,
to drive 3-Pin Latching Solenoids, up to 30 volts DC.  It pulses their ON pin, and OFF pin to control them.
It has many isolated digital inputs, outputs, voltage monitoring inputs, and isolated 4-20mA sensor inputs.

This -9D version has 2 isolated  Latching Solenoid Drivers.  An MODBUS command can be used to
send a message into the RAZN to pulse the ON pin, or the OFF pin at the duration you want to pulse it at.
Autonomous features can be setup to limit the pulse duration time, and also limit the maximum on-time duration.

The other RV-N55-4D version has latching solenoid driver outputs to drive 2-pin latching solenoids.
Here is the architecture of 3-pin latching solenoid:
A pulse on the ON pin, turns it on. A pulse on the OFF pin turns it off.

Here is the architecture of 2-pin latching solenoid:
A positive DC voltage pulse turns it on, and an reverse negative pulse turns it off.

The RV-N55-9A is lower cost RTU to control solenoids, relays, lights, valves, pumps, or whatever.
There are analog input sensors, and two isolated digital inputs for use in remote areas and wireless links.

Ethernet interface is an option, but most of these miniature SCADA terminals don’t need Ethernet.
RS-485 is available on this, VHF, UHF, or ISM band data radios can be incorporated into the RAZN
to have Long-Range RF wireless data links.
