High Precision 55 Channel Battery Monitoring Module RS485 Communication DCXJ-55

The DCXJ-55-3 is an industrial-grade high-precision battery monitoring module engineered by Shijiazhuang Tonghe Electronics for global large-scale energy storage and power systems. This advanced module specializes in 55-channel 2V individual cell voltage monitoring and dual-channel ambient temperature sensing, supporting multi-module expansion for large battery packs exceeding 55 cells.

• Wide DC power supply range (88~286VDC, rated at 220VDC)
• Low power consumption under 10W
• DIP switch-configurable for NTC/LM35 temperature sensors
• RS485 communication interface with 4-bit address DIP switches
• Multi-module expansion capability for large battery systems
• Excellent environmental resilience for industrial applications

Designed to meet global industrial power standards, the DCXJ-55-3 enables quick integration into various international power architectures. The module operates stably in indoor industrial environments (-10℃~40℃, 95% RH @ 40℃±2℃, altitude ≤2000m) and resists conductive dust and corrosive gases.

Widely used in large energy storage plants, power equipment battery packs, and DC UPS systems, the DCXJ-55-3 provides global clients with a highly adaptable, reliable, and easy-to-integrate monitoring solution that comprehensively safeguards battery operation while optimizing maintenance efficiency and cost control.
