ControlByWeb Ethernet I/O products can be easily integrated into SCADA and industrial automation systems (using Modbus / TCP) or they can be used as single, stand-alone devices right out of the box. You can even use our products in pairs (peer to peer) to send I/O over IP networks without using an external controller.

Data Acquisition and Remote Monitoring

ControlByWeb Ethernet I/O solutions provide accurate data acquisition over IP networks. Our data acquisition devices allow you to measure and monitor discrete/analog signals from a remote location.
