ControlByWeb

I/O controllers for water, level, and pump control in the water/wastewater industry. Control solutions for water treatment plants, wastewater treatment plants, irrigation water systems, and water pumping stations.

I/O Experts for the Water/Wastewater Industry

Our programmable I/O devices are perfect for water projects of all kinds. Our customers use our controllers for clean water, raw water, irrigation, and wastewater applications large and small. We focus on manufacturing industrial-grade I/O with inherent flexibility and affordable reliability.

ControlByWeb devices are easily programmed in a no-code setup menu that is built into the device itself. The non-proprietary platform communicates using industry standard Modbus TCP/IP and a variety of other open-code languages to ensure maximum compatibility. They require no cloud software or Internet connectivity to function as a programmable logic controller for nearly any application.

These attributes make our I/O modules ideally suited for the water/wastewater industry. Critical control functions demand reliability, varying scopes require flexibility, and the vast array of aging infrastructure and new technology makes our open platform a big advantage.

Scalable I/O Solutions

Our expandable I/O modules let you mix and match to create your ideal control solution. Our devices are used as stand-alone controllers, as RTUs in larger control systems, or as a process control system. Whether you're installing a simple duplex lift station or a large treatment plant, ControlByWeb is a great fit.

Remote Ready

All you need to view your control settings and process data is a web browser. Connecting your device to the Internet will allow you to monitor and control your processes anywhere in the world. Our devices communicate using Ethernet and standard networking practices and equipment and will work with your private network, Internet service, or your cloud.

Rural Water Systems

Our devices are more affordable than similarly capable control devices. We make sure of it through the way we operate as a U.S. business, and through keeping our solutions simple and purpose-built. This means we offer greater access to process control for rural water systems that are traditionally plagued by lack of funding and water quality challenges.

One rural water treatment plant upgraded to our X-600M platform from their old SCADA system. It cost them a very modest $10,000 when they expected to spend $100,000. Learn more here.

Common Water Problems


problem checkmark

Closed Proprietary Systems

Proprietary systems are unfortunately commonplace in the water industry, forcing budget strapped municipalities to upgrade more equipment unnecessarily.

problem checkmark

Difficult Programming

Many organizations don't have the technical staff to program industrial controllers and have to hire programmers to make any adjustments or program any replacement units.

problem checkmark

Too Expensive for Rural Water Systems

Rural community water systems experience more water quality violations due to budgetary constraints and cannot afford expensive control systems.

ControlByWeb Water Solutions

Open Compatibility

Our devices use on-board logic that is accessed on a standard web browser and communicate with control systems via Modbus TCP/IP, XML, and other protocols.

No-Code Programming

ControlByWeb I/O modules can be programmed using drop-down menus to control relays, trigger email and text alerts, log sensor data, and more.

Affordable, Self-Contained Solution

Each module costs a few hundred dollars and makes water/wastewater control projects much more affordable for budget-constrained communities.

How our Customers Use ControlByWeb™ Products

Simple Stand-Alone Device

A single ControlByWeb device can operate on its own as long as it has an IP network for communication. Data can easily be accessed on a local network or via the Internet. Ideal for remotely monitoring a single site or multiple facilities.

Stand-Alone I/O Device

Integrated in Control Systems

Integrate ControlByWeb devices throughout your advanced control system using Modbus TCP/IP, XML, SNMP and more. ControlByWeb devices act as an RTU in industrial control systems of all sizes and complexities.

Remote Terminal Unit

Complete Control System

Create a fully functional control system using ControlByWeb I/O devices and sensors. Our X-400 and X-600M with expandable I/O and programmable logic are ideal for a control system you can monitor & control locally or remotely.

Frequently Asked Questions About the Water/Wastewater Industry

Answer

Our expandable I/O platform is ideal for creating a PLC-like control system. The X-400 and X-600M are both capable control modules with many options for expansion I/O. The X-400 is ideal for small to medium-sized installations while the X-600M handles more I/O points per controller and features a graphing function that can be display directly on the Dashboard as a basic SCADA.

Answer

No special network equipment or gateways are needed. Our devices simply need to have sensors, pumps, motors etc. wired correctly to the appropriate inputs and outputs. If you want network-based or remote monitoring, then an IP network is required. However, the devices will provide control logic even without network connectivity.

Answer

We make programmable I/O modules and put our focus there. However, we carry a variety of level sensors from manufacturers we trust and offer our customers the same great pricing on these sensors for a more convenient procurement experience.

These sensors include:

  • VEGAPULS Non-Guided Radar Transmitters
  • Ultrasonic Sensors
  • Submersible Pressure Transducers
  • Float Switches

However, our I/O devices are compatible with a wide range of level, flow, pressure, pH, turbidity, and temperature sensors. We have devices that are compatible with analog signals like 0-10VDC or 4-20mA, as well as Modbus RS-485 communication. Of course, we are compatible with float switches, pressure switches, or any limit switch as well.

Answer

Our X-420 is a great starting point. It's great for common applications like duplex pump control in places like lift stations. It has 4 analog inputs that can be programmed as digital inputs as well. It also has two digital I/O that can be configured as inputs or outputs. It's very flexible and works in a variety of pump control scenarios. The X-410 is similar, but without analog inputs and with 4 relays. It's ideal for pump control that uses float or limit switches. Our X-400 with a few expansion modules is great for pump control in a treatment plant or in a larger pump station.

Answer

Our I/O devices communicate with PLCs, DCS controllers, and SCADA software via Modbus TCP/IP, XML, JSON, and others. There is nothing proprietary about our devices. Any control system that can accept one of those protocols should work just fine.
