Description
BL102 PLC IoT gateway converts Modbus RTU, Modbus TCP, Siemens, Schneider, Mitsubishi, Omron, Delta PLC protocols to MQTT protocol. The gateway supports Ethernet, WiFi, or cellular networks(4G) transmission, ensuring that data is transmitted to AWS, ThingsBoard, IgnitionSCADA, and other cloud platforms stably and reliably.

Key Features

Robust Hardware Configuration

  • Powerful Core: 300MHz ARM processor + Linux OS, 128MB RAM + 64MB Flash memory.
  • Rich Interfaces: Connect 10/50 devices simultaneously, collect 512/4000 data points.
  • Dual-channel RS485/RS232 (baud rate 2400-115200bps, 7/8-bit data bits adjustable).
  • Supports cascaded switch device acquisition with high scalability.

Intelligent Connectivity

  • Triple-Network Backup: 4G (optional), WiFi (optional), and Ethernet with automatic failover to 4G when wired fails
  • VPN Support: OpenVPN for secure data transmission
  • Network Redundancy: Auto-switch to 4G/WiFi ensures uninterrupted operation 

Remote O&M Powerhouse

  • Remote configuration and firmware upgrades reduce on-site maintenance
  • PLC remote debugging (program upload/download)
  • Real-time device status monitoring (chip temp, memory, port status, 4G signal)

Industrial-Grade Reliability

  • Wide Voltage Input: DC 9-36V with reverse polarity protection
  • Extreme Environment: Operates at -40℃~55℃, 5~95% RH
  • Certifications: CE/FCC/RoHS/EMC Level 3 (ESD ±8kV/EFT 1kV)
  • Dual Watchdog: Hardware + software self-recovery mechanis

Typical Applications

Smart factory: PLC/sensor data is uploaded to the cloud to monitor production line status in real time.
Energy management: Modbus data of electricity/water meters are aggregated to the energy management platform.
Remote operation and maintenance: 4G networking enables remote diagnosis and maintenance of equipment in remote areas.
