DESCRIPTION:

The Franklin Grid CGBC-350 is a CELLGUARD™ Wireless Base Coordinator Unit (BCU) designed for centralized management and communication of Franklin Grid wireless battery monitoring systems within utility substations, telecommunications infrastructure, UPS systems, switchgear, renewable energy installations, and data centre backup power environments. The BCU coordinates battery sensor activity, collects operational data, manages alarm thresholds, and communicates with the CONVERGE™ web interface for remote battery infrastructure supervision and predictive maintenance analysis.

The CGBC-350 supports wireless mesh communication with CELLGUARD™ battery sensors and is capable of monitoring up to 16 battery strings, up to 300 batteries per string, and up to 600 sensors per Base Coordinator Unit depending on deployment architecture. The system captures battery voltage, temperature, conductance, strap resistance, string current, and discharge event data for continuous 24/7 remote battery state-of-health monitoring applications.

The integrated embedded webserver and CONVERGE™ interface provide remote system configuration, alarm management, battery analysis, firmware management, discharge reporting, and live infrastructure status monitoring through Ethernet TCP/IP connectivity. The BCU supports communication protocols including Modbus TCP/IP, SNMPv3, and MQTTS for integration into SCADA systems, building management systems, and third-party infrastructure monitoring platforms.

The CGBC-350 operates from 9 VDC to 12 VDC at 800 mA and features dual USB ports, Ethernet connectivity, UART communications, analog and binary alarm inputs, relay alarm outputs, and integrated wireless RF communications using 802.15.4 compliant 2.4 GHz wireless networking. The platform supports field-upgradable firmware, remote network configuration, string current monitoring, and automated discharge data collection for advanced stationary battery asset management applications.

The system is suitable for VRLA, VLA, and Ni-Cd stationary battery monitoring applications across utilities, telecom facilities, data centres, rail infrastructure, industrial DC systems, and critical backup power environments requiring continuous operational visibility and predictive battery maintenance capability.
