Who We Serve
ControlByWeb exists to serve the engineers, technicians, and professional integrators building the backbone of the Industrial Internet of Things (IIoT). Our mission is to make industrial control and data acquisition more intuitive, more robust, and more cost-effective without compromising on control or security. We give professionals the tools they need to deploy field-hardened, flexible systems with total confidence.
Where We Came From
Founded in 1999 as Xytronix Research & Design, ControlByWeb shifted to manufacturing our own line of I/O controllers. This started with the pioneering WebRelay to meet the growing demand for simple, scalable remote monitoring. Since then, ControlByWeb has grown into a trusted name in industrial controls with a full suite of modular and standalone logic controllers.
From OEM solutions to custom integration, we’re here to help professionals solve tough problems with elegant, engineer-grade tools.
