Description
The ControlByWeb® X-418-E is an industrial-grade, 8-channel analog input controller designed for high-precision monitoring of process variables such as tank levels, pressure, flow, and current. Featuring Power over Ethernet (PoE) capability, the X-418-E simplifies installation by allowing the device to be powered directly through the Ethernet cable, making it an ideal solution for deployments where dedicated power infrastructure is limited or hard to reach.
As part of the 400-Series, the X-418-E delivers accurate, 16-bit analog-to-digital conversion without the need for external software or licensing fees. It features a built-in web server and a no-code Task Builder, enabling users to create custom automation logic, dashboards, and data logging directly through a web browser. With native support for Modbus TCP/IP, MQTT, SNMP, and REST, the X-418-E integrates seamlessly into SCADA, PLC, and IIoT systems, providing a secure, scalable, and vendor-neutral solution for facility and process monitoring.
Key Features
- Power over Ethernet (PoE): Simplifies installation by powering the device directly through the Ethernet cable (also supports 9–28 VDC).
- 8 Multi-Function Analog Inputs: High-resolution (16-bit) inputs configurable for single-ended or differential operation.
- Configurable Ranges: Channels 1–4 support both voltage (±1.28V to ±10.24V) and 4-20mA current; channels 5–8 support voltage.
- 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 I/O data across multiple ControlByWeb controllers without a central server.
- Flexible Data Logging: Scheduled and conditional logging with automated FTP exports or email alerts.
