Price Guide (Inc GST): POA

The BDL combines 0.1% measurement accuracy and advanced analysis techniques to display, within seconds, the condition of all batteries in an installation.

Simple to use and flexible, the BDL provides unsurpassed battery monitoring capabilities to assist in obtaining peak battery performance and long service life.


  • Accuracy of voltage measurements: better than 0.1%
  • Four-digit readings
  • Measures reversed-polarity batteries
  • In-built system diagnostics via 16-bit microcontroller
  • Automatic battery analysis during discharge
  • Five user-definable tolerance bands
  • Flexible design allows easy expansion
  • LED and audible alarms for indicating battery out-of-tolerance or BDL fault
  • Voltage-free C/O contacts for remote alarm monitoring
  • Monitors battery room ambient temperature
  • Records scan date and time
  • RS232C, RS485 and TCP / IP interfaces for networking or connection to BMS or PC, personal computer or modem
  • User-definable configuration and operating parameters (via personal computer) for quick BDL set-up to suit any battery installation and usage
  • Fast sampling rate - 200 batteries in just 5 seconds (1 second with special configuration)
  • Sampling intervals programmable from 5 seconds to several hours
  • Periodic maintenance logging and analysis intervals programmable from 1 minute to 1 month
  • Current-limited battery connectors for safety
  • Conforms to QA standard ISO9001
  • Multiple battery strings
  • Monitors up to 16 banks
  • Simultaneous bank scanning
  • Multiple I/O communications capability
  • Automatic and continuous logging and analysis

The BDL is a stand-alone system designed to continuously monitor one or more battery banks. Multiple units can be easily interconnected for monitoring a practically unlimited number of batteries.

On detecting a discharge, the BDL will automatically log battery voltages and currents for the duration of the discharge / recharge cycle and print an analysis report. The report lists any out-of-tolerance batteries in user-definable deviation bands (typically: 2%, 5%, 8%, 10% and 20%).

Logging can also be performed at user-programmable intervals, automatically in response to an out-of-tolerance condition, or manually via a pushbutton on the BDLís front panel.

The BDL is capable of scanning around 1000 batteries and storing up to 4000 sets of out-of-tolerance data. Battery data can also be logged and displayed locally on a personal computer or transmitted via modem to Thyconís service computer for further analysis.

Connect to your LAN via the TCP / IP 10 BaseT connector and monitor and download data from the BDL to any PC connected to your network. Then use your browser to view data. No propriatry software is required to view and or remotely operate the BDL.

Dual source power supply capability ensures that when a single BDL is shared between operation is no longer limited to a specific supply being available for correct operation. Power as dual or single 240 V AC, 110 V DV, 50 V DC or 24 V DC are available.

Simple installation

BDL installation is inexpensive and generally does not require disconnection of the batteries. Configuration changes can be made quickly and easily with the aid of a personal computer.

BDL settings and operating parameters such as bank names, number of batteries per bank, scanning intervals and deviation bands are all user-definable.
