Isolated IOs in the Remote Autonomous Zone Node   RTU/PLC
Latching 2-Pin Solenoid is controlled.

The RV-N55-4 RAZN is an RTU automated peripheral with many Isolated Inputs and Outputs. And can control 2-Pin Latching Solenoids.

This RV-N55-4 RAZN has 12 IO features, and 8 of them are totally Isolated from the RAZN and from each other.
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.
A MODBUS Latching Terminal command was created to pulse Latching Solenoids reliably with MODBUS commands.

Drive a 2-Pin Solenoid with the Double Action Dual pin (DSD) drivers, and Autonomous duration limitations in the RAZN will pulse the Solenoid correctly.

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.

Your system can send messages to the RAZN to control Latching Solenoids, by pulsing them ON or OFF.  The Autonomous features in the RAZN makes this system
very safe. If for some reason, the OFF pulse doesn’t take place, the RAZN will Autonomously send the OFF pulses to be safe.

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.

You can control it with MODBUS messages to do what ever you want it to do, and it can also have it autonomously do what needs to be done.
This makes your system safer because it will do things if the controller or network fails.

RAZN   RV-N55-4   Isolated Product Features

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

This complete solution can remotely control things that are even miles away.
It contains Two 12 pin Terminal ports, (24 pins) to implement the 12 IO features,
and have  8 IOs that are totally Isolated over hundreds of volts.

Latching Solenoids can be controlled by this RAZN version.

On Ethernet terminal port  processes MODBUS TCP messages.
Another terminal port links to the Radio Modem in this RAZN, and communicate over-the-air to other RAZNs.

High Isolation Inputs And Outputs

RAZN uses a TI 12 bit differential voltage sensor (the best in the world ADC) to measure voltage with 1M resolution. It can also measure current and 4-20mA current with over 1M resolution.
The RV-N44-7 version uses  23 bit High Resolution interface for the Sensors to Monitor   Detailed information about the sensor inputs is on the Terminal Information page..
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.

The RV-N55-4 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.
A MODBUS Latching Terminal command was created with 2 registers control via MODBUS. Set first Reg. to specify the outputs to pulse, and the next Reg. specifies the pulse durations in mS.

Control Latching Solenoid

The RV-N55-9D can controls a 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.

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.
The RAZN can Autonomously send pulses to a Latching Solenoid to make sure it gets turned off.
And the RAZN can be configured as you want, to make sure outputs have limitations: Max./Min. on or off time, Max./Min. changes per minute, hours, days, Max./Min. pulse time.

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-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-N55-4D  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 RV-N55-4D 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-Ppin 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.

Same as the RV-N55-4D

Except only Terminal A is on the product.

Terminal B is not on this  RV-N55-4B version, so
it is lower cost, and lower power consumption.

On terminal A, there are:

2  Isolated DSD Solenoid driver IOs to drive 2-pin solenoids.
2 Isolated AI analog Inputs to measure voltage or 4-20mA sensors.
The input voltage for the solenoid driver is on pins 11 and 12.
