Super Control and Data Acquisition (Sensor Terminals Converts)
The RAZN Devices is a durable, loop-powered 4-20mA Display for use in Process monitoring applications.
The list of terminal features here are available on all RAZN devices.
Raveon’s Waterproof Battery powered Outside Get Good Information OGGI device has many IO terminals also.
The Remote Autonomous Zone Node RAZN have many Input/Output capabilities. RAZN can monitor 4-20MA, Voltages, Digitals, Temperature, and Vibration.
This page describes all the types of terminals available on Raveon’s products (RAZN and Tech Series) with SCADA terminals and General Purpose IOs.
RAZN devices have all of these terminals available, and some Tech Series radio enclosures use some of these.
The Fundamentals of 4-20 mA Current Loops at Sensors.
When it Loops, the RAZN product monitors and spots the big loop. It sends this info to you.
And for Safety, you can setup the RAZN to Automatically do something Safe about Loops.
Transmitter
Whatever the sensor is monitoring, in milliseconds, it converts its measurement into a current signal, between four and twenty milliamps.
An transmits to your system, with: RS478, RS232, Ethernet, or Frequency Transmit. RAZN Frequency Bands.
The RAZN can be mounted in various configurations. Inside the RAZN a Data Radio can be used if you want a Frequency Transmitter.
Power Source
The RAZN can output DC power to run the SENSOR. The power supply voltage at least 10% greater
Server Environment Monitoring System RTD Sensors RTD Temperature Sensor.
Transmitters compatible with Converters. Use to extend sensor up to 2 miles from the RAZN

Input Output (IO) Terminal Block Descriptions RAZN Has
The Remote Autonomous Zone Node (RAZN) products Raveon creates have all of these IO features. The RAZN version have 24 IO ports on the terminal blocks.
Here is a description and diagrams of the IO terminals available on various RAZN terminal. Shows RAZN IO Terminal Versions web page.
Modbus RTUs have IO terminals like this, and Raveon’s RTUs have these.
For SAFE Systems: Each product version of Raveon’s RAZN have Raveon’s GPIO interfaces on radio modems with a variety of different input and output terminal block function pins with a myriad of different features available.
The Myriad of IO features the RAZN is shown of RAZN IO Terminal Versions web page. RAZN has many internal features to be Super Safe. It is more safe than any other Sensor Monitor that monitors 4-20mA.
To be safe, it has a Timer-Operation-Action (TOAA) feature to make a city or state super safe. The TOAA feature and be configured by you, so that if something goes Bad in your area, the RAZN will Automatically do Save IO features.
The RAZN could turn off (Power or Gas) is something is gad. It a Computer Failed, and the it cant talk to a sensor, so the RAZN can monitor Sensors and Control other IO features the way you want.
When you setup the TOAA feature, it is to be SAFE. So, if your computer broke, or your cables got cut, then the RAZN will automatically monitor Sensors, and then switch other Output features to be safe.
Our Tech Series Radios have many IO pins to monitor SENSOR TRANSDUCER and Converters. They can monitor 4-20mA or large Voltages.
If you need some other terminal IO feature, contact Raveon and we will be glad to create new IO functions. If an IO pin has a Configuration variable, the letters is the name code code for the particular IO pin is how they are referred to and configured in commands.
All pins are heavily protected against noise and ESD and can be configured/calibrated to program the RAZN. MODBUS commands can read and control these IOs.
