Description
The ControlByWeb® X-406-I is an industrial-grade, 4-channel 1-Wire multi-bus module designed for scalable temperature and humidity monitoring. Supporting up to 64 sensors (16 per channel), it provides a comprehensive solution for large-scale environments such as warehouses, cold storage facilities, greenhouses, and data centers. Engineered for reliability, the X-406-I utilizes a 9–28 VDC power input, making it a robust choice for standard industrial control panels and process automation environments.
As part of the 400-Series, the X-406-I features a built-in web server and a no-code Task Builder, enabling users to create custom automation logic, dashboards, and data logging without the need for external software or recurring licensing fees. With native support for Modbus TCP/IP, MQTT, SNMP, and REST, the X-406-I integrates seamlessly into SCADA, PLC, and IIoT systems, providing a secure, vendor-neutral platform for critical environmental data acquisition.
Key Features
- Large-Scale Monitoring: Four independent 1-Wire buses supporting up to 64 total sensors (16 per channel).
- Browser-Based Interface: Complete device management, configuration, and real-time monitoring via any standard web browser.
- No-Code Logic Builder: Create powerful automated sequences and conditional logic using the intuitive Task Builder.
- Industrial Protocol Support: Native integration with MQTT, Modbus TCP/IP, SNMP, XML, and HTTP.
- Peer-to-Peer Communication: Easily share sensor data across multiple ControlByWeb controllers without a central server.
- Secure & Reliable: Cybersecurity-focused design without a built-in OS or file system, reducing attack vectors.
- Flexible Data Logging: Scheduled and conditional logging with automated FTP exports or email alerts.
