The FineJoin E1684B is an industrial RFID gateway controller engineered for seamless PLC and automation system integration. Supporting standard Modbus TCP and Modbus RTU communication protocols, it acts as a high-efficiency bridge between the field level and control level. With its rugged IP67-rated design and innovative M23 integrated port for combined power and network connection, the E1684B delivers high reliability in harsh industrial environments.
- 4 Independent RFID Channels: Supports simultaneous or individual connection of HF and UHF RFID readers (M12, A-coded, 5-pin) for decentralized data collection.
- Industrial Protocol Compatibility: Seamlessly integrates with major PLCs and controllers via standard Modbus TCP/IP.
- Single-Cable Integration: Utilizes a heavy-duty M23 connector (7/8" thread) to deliver both 24V DC power and Ethernet network interface, reducing wiring complexity.
- Comprehensive Circuit Protection: Built-in reverse polarity, 3kVA surge, overvoltage (OVP), and overcurrent (OCP) protection to safeguard automation assets.
- Smart Fault Diagnosis: Features multi-status LED indicators for real-time operational monitoring and rapid troubleshooting.
