Modbus RTU Based Relays, Gateways, & Data Loggers
Capture and use data at the edge with Modbus-based relay and input devices from ControlByWeb®. Our built-in browser-based UI allows you to program conditional and scheduled logic, without code, to easily control relays, data logging, email alerts, Modbus registers, and more through simple drop‐down menus.
The ease of use and capability of ControlByWeb devices make them ideal for multiple applications such as level and flow monitoring, temperature monitoring, lighting control, current monitoring, and more. Contact us today to discuss your application with a qualified Sales Engineer.
Fully Capable IoT Controllers
ControlByWeb offers a range of flexible and feature-rich I/O devices that are able to control relays, monitor inputs, and more. ControlByWeb devices provide all the benefits of a standard Input/Ouput controller while offering additional advantages and capabilities for the Industrial Internet of Things (IIoT).
Built-In Firmware
ControlByWeb Edge Controllers feature a lightweight, easy-to-use interface. Building custom logic is as easy as navigating drop-down menus.
Data Logging
Save edge data logs to a separate computer or server. Program your Edge Controller to send log data via email or FTP.
Peer-to-Peer Networking
P2P networking is available between ControlByWeb relays, allowing for shared I/O and remote inputs and relay control.
Inherently Secure
ControlByWeb devices have no native OS or file system, making them less prone to vulnerabilities.
Expansive Communication Protocols
ControlByWeb devices support more than just Modbus. They’re also capable of using HTTP GET, MQTT, XML, JSON, SNMP, and TCP/IP.
ControlByWeb Cloud
400 Series devices can utilize the ControlByWeb Cloud to remotely monitor and manage multiple locations.
Application Spotlight: Big D Companies
Level & Flow Monitoring in Oil & Gas
The Oil and Gas industry relies on water for drilling, hydraulic fracturing and refining. It’s also a natural byproduct of extracting hydrocarbons from the earth. Needless to say, the supply and waste management of water in the O&G industry is critical. Level and flow are important measurements for managing this most vital resource.
For flow monitoring, Big D uses inline flowmeters that trip a contact for every barrel that passes. The trip is very momentary, lasting only a fraction of a second. The X-410 not only logs the event, but can immediately pass this information on to their custom cloud-based SCADA.
A variety of sensors are used in the oilfield for tank level monitoring, from switches to continuous level transmitters. In the case of a level switch, often used by Big D, our X-410 is a fantastic tool for monitoring the contact(s) in the switch. For level transmitters, our X-420 is great for analog signals and our X-404 is perfect for Modbus RS-485 signals. Level measurements and tank status can be remotely access through port forwarding, our Cloud service, pushed to your own cloud environment or via our smartphone app.
ControlByWeb programmable IoT controllers provide an easy-to-deploy, flexible data acquisition and controls platform for often remote and/or temporary locations.
