A Remote Zone Node (RZN) is for smart SCADA and Telemetry node with general purpose control capability in a compact, cost-effective package. RZN can switch on/off 8 AC and DC power outputs, and convert up to four analog devices, 8 digital inputs, and 2 switch inputs, into: EtherNet/IP or Modbus-TCP. This is a RTU and has many more IoT and wireless features than most traditional RTUs.

Reduce your system cost by using Remote Notes With Wireless modems built in.

Switched AC and DC power connections and Flexible IOs

User Wires (Ethernet, RS485, USB)  or  use Wireless (ISM, LoRa, UHF, VHF)

Optically Isolated switched power outputs and reverse power protected.

Flexible Input/Output Options:  Digital, Switching AC or DC Power, Voltage, Current, buttons,…

The RZN is a Remote Terminal Unit (RTU)  used to monitor and control a variety of devices and systems. An RTU is similar to a programmable logic circuit (PLC) but has more in-depth functionality. A  key component of a the RZN is the ability to send and receive real-time data.

 Simplified SCADA for Less Complex Applications

This simplified RTU communicates with your control center as quickly as you need to know about the status of things connected to it. The sooner you get the information, the faster you can fix the problem and avoid negative consequences.

The Industrial Internet of Things (IIoT) features of this simple smart device offers opportunities to enhance your operations across manufacturing, energy, agriculture, transportation, water utilities and other critical infrastructure sectors of the economy. It improves the way you collect, analyze and share real-time information to help your organization make better decisions. The RZN enables machines and equipment to resolve potential failures before they become a catastrophe. It allows remote objects in remote zones to operate autonomously while being monitored by personnel from remote locations or locally.

With this easy-to-deploy IIoT solution, you can monitor and control your system from anywhere. And The Remote Zone Node’s smart wireless interfaces enable you to monitor and control thousands of things using one Ethernet connection or one cellular connection, to greatly reduce your connectivity costs.

  • To connect things to internet cloud servers or your private servers, the Ethernet or wireless connections can pass the status of switches and sensors to your servers.
  • Control valves and pumps. Turn on and off irrigation devices.
  • Monitor water sensors, and report their status and report emergency information.
  • Monitor analog sensors such as temperature, pressure, current, voltage,… connect them to the Analog inputs

Use the Remote Zone Node (RZN) to control your devices with Ethernet connectivity or Long range wireless.

The RZN can control and also relay messages onward to very remote areas with more RZNs in them.

Efficiently Control Nodes All Around a CITY, STATE, or COUNTRY.

Smart and High Performance

Designed in 2018, the ARM processor is much higher performance and lower power than RTUs design 10 years ago. CPU processing power provides accurate data analysis and communication for the most critical, and demanding SCADA applications to ensure optimal operation.

The RZN is designed to use a variety of digital, analog, and switched power interfaces so you are never locked into proprietary solutions. The flexible communications capability enables the RZN to connect with hundreds of local devices, analyze the data, and send that status information to various other locations. Data transmission and processing is supported simultaneously across multiple communication media and industry standard data protocols including MODBUS.

Real-Time Process Automation And Robust Communication

The RZN’s General Purpose IOs (GPIOs) can be sedup in any way you want. Each GPIO has many configuration options.

  1. Digital Inputs
  2. Digital outputs
  3. Open drain switch output
  4. Voltage monitoring
  5. 4-20mA input to measure current
  6. Push-button digital inputs.

The RZN also has switched power capability to pass on DC or AC power to many different products, valves, relays, lights,…

The communication is the most robust in the industry. With some many interface options, it will work with anything, and because it is a smart Remote Terminal Unit, it also can pass on messages to other devices in the area using RS-422, Ethernet, LoRa or long-range narrow-band wireless modems. All of these features can in included int he RZN model you acquire for your system.
