RS485 / Modbus RTU Wired Devices

Build reliable wired networks with professional RS485 / Modbus RTU devices engineered for industrial automation and IoT. RS-485 is a robust, half-duplex serial standard that runs over simple 2-wire cabling for distances up to 1,200 m, making it ideal for connecting legacy machinery, precision instrumentation, and field equipment to modern monitoring systems.

This collection brings together industrial-grade Modbus RTU hardware for high-reliability data acquisition:

• Sensors & transmitters: temperature, humidity, CO₂, current, and energy metering
• Digital & analog I/O modules: remote inputs/outputs for control and monitoring
• Gateways & bridges: RS485-to-Ethernet, Wi-Fi, and MQTT for cloud integration
• Controllers & PLCs: programmable logic for automation tasks

Every device speaks the Modbus RTU protocol with configurable baud rates and addressing, so it drops into existing SCADA, BMS, and PLC systems. Common applications include smart metering, HVAC and building automation, energy monitoring, and industrial process control.
