Franklin CELLGUARD CGS3-12V-WD Battery Sensor
The Franklin Electric Energy Systems CGS3-12V-WD Battery Sensor module is a critical data acquisition component designed for the CELLGUARD™ Wired Battery Monitoring System (BMS). It interfaces with the CGBC-350-HWD Base Coordinator Unit (sold separately) to measure and analyze the voltage, temperature, and internal resistance of individual 12V batteries. Collected telemetry data is subsequently uploaded via the integrated COM port for comprehensive system-level analysis.
Key Features & Interfaces
- Measurement Capabilities: Voltage, temperature, and internal resistance.
- Power Requirements: Powered directly by the monitored battery (12V @ 7mA).
- Integrated Components: Status indicator light, battery connection port (for battery cable harness connector), and dual communication ports (COM1/COM2).
- Compatibility: Designed exclusively for 12V lead-acid batteries and the CELLGUARD™ Wired BMS environment.
Installation Warning
Warning: This sensor must be installed strictly on a battery matching the appropriate sensor voltage rating (12V lead-acid battery). Installation on batteries with differing voltage ratings will result in unit damage.
