Data Logger & Monitor


For Battery Discharge Curve Logging and Battery Monitoring Alarm System

DLM Series Data Logger

DLM-09 Logger Datasheet


  • Easy to set up.
  • Intuitive to use Application software.
  • Selectable “End Voltage” from 1.55V to 1.90V per
    Cell, (or equivalent for blocs), which effectively
    becomes a LVD function with output to disable a
    Manatronics Electronic Load. Every Cell / bloc is
    monitored for “End Voltage”, which prevents deep
    discharge and possible battery damage.
  • Common input modules for 2V, 4V, 6V and 12V
    blocs. (i.e. no need to buy/change/store modules).
  • Designed for 12V, 24V, 48V and 110V Battery
  • Standard unit has 9 channels, (for Cell/Monoblock inputs). Expandable up to 127 channels.
  • Option for Ethernet / LAN connection.
  • Option for USB connection


The Data Logger/Monitor has been designed to operate on 12V, 24V, 48V and 110V battery systems, with optional inputs for higher input Voltages, up to 550V. The Data Logger/Monitor is completely powered from the Batteries, and therefore a mains supply is not required. Therefore tests are not terminated part way through by a temporary mains power outage. The unit is lightweight and is completely portable. The Data Logger/Monitor may be left on site, unattended, for extended periods of time for data collection. Or used permanently as a Monitor / Alarm system.

The standard Data Logger/Monitor is built to accept up to 9 inputs from Cell / blocs and comes complete with a Master Input Module. (There are options to increase the number of channels up to a total of 127 Channels at the time of ordering). These can all be logged together with “Temperature”, “Battery Discharge Current”, “Overall Battery Voltage” and “Total Interconnection Voltage”. As well as recording all of the inputs, the relative time is also logged, e.g. 1 minute, 30 minutes, 60 minutes etc..

The Data Logger/Monitor has two modes of operation, Battery Discharge and Monitor Mode. In Battery Discharge mode the unit will log all cell/bloc Voltages at programmed intervals as well as “Temperature”, “Battery Discharge Current” and “Overall Battery Voltage” and “Total Interconnection Voltage”.

The logger is initially set up via a local or remote Laptop / PC, after which the Laptop may be disconnected and the logger will continue to function in its present mode. In discharge test a Laptop may be reconnected after the test has finished and the data collected downloaded to the laptop. In Monitor mode the logger will continue to activate its alarm output contacts should an alarm condition occur. The Laptop may be reconnected at any time for real time updates of all readings and alarm status.

The Logger is housed in a light weight 19 inch Rack mountable, 1U size case (for up to 79 cells) and is very Cost effective. The unit has been made to be very portable and is a Rugged and Reliable Design. The unit is ideal for the standard 3 and 5 hour discharge testsand long term monitoring.
