Digital I/O Modules

Use Digital I/O modules to remotely monitor digital input state or control relays based on input state. ControlByWeb digital input modules are high quality, easily programamble and work peer to peer or with cloud connection.

Data Acquisition & Remote Monitoring

ControlByWeb provides an easy and reliable way to affordably monitor and control remote assets and/or processes. Our Ethernet I/O products combine traditional automation hardware with the flexibility of IP networking.

Each device has a built-in web server, and can be accessed via a standard web browser over a LAN, WAN, or via the Internet. There is no special software or app required, no drivers to install, and no monthly subscriptions.

Peer-to-Peer Communication

With our Peer-to-Peer communication and remote control capabilities, our Ethernet I/O devices are ideal for remote relay control. You can control a relay remotely based on an input on a ControlByWeb device (peer-to-peer) or you can remotely turn on pumps, open gates, or lock buildings via the built-in web server on each device.

Features

  • Email/Text alerts
  • Control relays based on preset thresholds
  • Custom Logic – No programming required
  • Built-in web server
  • Configurable control and status web page
  • Modbus/TCP support
