Remote Autonomous Zone Node (RAZN)
Many Versions with: Input and Output (IO) Terminals
This Remote Autonomous Zone Node (RAZN) is a SCADA Remote Terminal Units (RTUs)
The RAZN is available in many different ways. Here is a list of all the IO terminal version that have already been created by Raveon.
Many different IO Terminal Versions
Most all RAZN devices look the sane. But there are many different versions for many different industries.
The large and smart system architecture that the RAZN can run, is shown on this page: Click Here.
Many RAZN IO Terminals have interface for the Sensors to Monitor.
Raveon’s RV-M55-E Ethernet Interface Data Radio Modem RV-N55-E Ethernet Radio can connect Wireless RAZNs to your network.
Raveon’s long-range data radio can communicate many miles, even up to 50 miles. All RAZNs have VHF, UHF and ISM band radio options.
Raveon’s RAZN has many Complete Solutions to automatically control things.
This Web Page shows: All of the IO Terminals and all hardware versions of the RAZN.
Most all RAZNs have two 12-pin IO terminals referred to as: Terminal A and Terminal B.
Each terminal has pin numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12.
And for SCADA communications, commands, and MODBUS messages, each terminal pin is assigned an IO number IO#.
The IO# is used to control, monitor, and communicate to the RAZN so the terminal with an IO# can be managed.
In this web page, the IO# are listed on each Terminal pin number.
A myriad IO terminal features and options are sown on: terminal IO pin options All of these are available in a RAZN.
The Multifunction Meters are analog inputs to measure either voltage or 4-20mA sensors, or measure current draw.
The AI input and the Isolated IAI inputs are these multifunction meters.
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.
