Description
The ControlByWeb® X-420-I is a versatile web-enabled data acquisition controller designed for flexible industrial monitoring and control. With 4 analog inputs, 2 configurable digital I/O, and support for up to 16 temperature sensors, the X-420-I gives engineers a compact and adaptable platform for a wide range of applications.
Built for stand-alone operation or integration with SCADA, PLC, and IIoT systems, the X-420-I includes an embedded GUI logic builder, browser-based dashboards, and open communication protocols for simple deployment without licensing fees or vendor lock-in. It is well suited for applications such as pump control, fluid level monitoring, and temperature and humidity monitoring.
Key Features
- 4 Analog Inputs: Supports single-ended, differential, and 4–20mA input types for flexible data acquisition.
- 2 Configurable Digital I/O: Use the digital points as inputs or outputs depending on the application.
- Up to 16 Temperature Sensors: Supports 1-Wire temperature sensing for environmental monitoring.
- Web-Based Dashboard: Monitor and control the device through a simple browser interface.
- No-Code Logic Builder: Create custom automation using intuitive drop-down menus.
- Peer-to-Peer Networking: Share I/O and link remote devices for expanded control capability.
- Robust Data Logging: Log critical process and environmental data for review and analysis.
- Open Protocol Integration: Supports HTTP, HTTPS, SSL, XML, MQTT, Modbus TCP/IP, SNMP, SMTP, and Remote Services.
