Smart Remote PLC I/O Gateway with MQTT and Modbus Protocols for Cloud Integration

IOy = PLC + I/O + Protocol Gateway + Serial Server
In the era of rapid development in industrial automation and the Industrial Internet of Things (IIoT), BEILAI Technology’s IOy series multifunction programmable remote I/O modules stand out with their modular design, high-precision data acquisition, and powerful edge computing capabilities. Compared to traditional solutions combining PLC + I/O + protocol gateway + serial server, they reduce costs by up to 80%, making them an ideal choice for industrial field data acquisition, control, and Industry 4.0 applications. Whether for smart manufacturing, energy management, environmental monitoring, or equipment operation and maintenance, the IOy series delivers stable, efficient, and scalable solutions.

Flexible Combinations, Endless Possibilities
The IOy series adopts a modular, freely assembled design, supporting any combination of 1-3 Y-series I/O boards to meet the diverse demands of various industrial applications:
◆High cost-performance — up to 80% lower cost than traditional solutions combining PLC + I/O + protocol gateway + serial server
◆8DI + 4AI + 2PT mixed configuration — simultaneously collects digital signals, analog values, and RTD temperature readings
◆24-channel DI/DO configuration — ideal for large-scale digital signal control
◆PWM + DI counter combination — perfectly suited for motion control applications
◆DI + DO + AI + AO + RS485 combination — a comprehensive solution for instrument data acquisition, serial device integration, and automatic control
From smart manufacturing and building automation to energy and power automation, a single modular setup covers 90% of industrial signal types!

Smart Edge, Beyond Data Acquisition
◆Data acquisition and protocol conversion — Collects data from smart meters via RS485, performs protocol conversion and logic operations locally, eliminating the need for a separate protocol gateway
◆Logic operations, arithmetic operations, and conditional triggers — Enables local IF-THEN control logic without a PLC for on-site automation
◆Multi-protocol support: Modbus RTU/TCP, MQTT, OPC UA — Seamlessly integrates with PLC, SCADA, MES, and cloud platform systems
◆Multi-protocol support: Modbus RTU, BACnet, IEC104, SNMP — Seamlessly interfaces with building HVAC systems, power, and energy automation systems
◆Edge computing capability — Executes real-time control processing at the device edge, reducing cloud server load
Typical Application: In smart production lines, quality judgments are completed directly at the edge, improving response speed by 300%

Simplified O&M, Seamless Connectivity
◆Dual Ethernet port switch function — Supports daisy-chain topology wiring, reducing the need for additional network switches
◆Web-based visual configuration — Quick 10-minute deployment with support for remote firmware upgrades
◆BLRAT remote maintenance — Enables real-time remote device status monitoring, configuration adjustments, and firmware updates, achieving zero-delay fault handling.

Industrial-Grade Performance, Stable and Reliable
◆Harsh environment adaptability: Wide operating temperature range of -40℃ to +85℃, certified by CE/FCC
◆Dual safety protection: 2KVrms electrical isolation and independent hardware watchdog for enhanced reliability
◆Military-grade EMC design: Easily withstands factory electromagnetic interference environments
