Download Data Sheet


The Battery MetricTM RM modules provide a packaging that allows for flexible installation in a variety of situations. The system is expandable to provide any number of channels.

Each module is a single channel and is available in several current and voltage configurations. The power supplies are external to the module which also allows a number of different powering situations. Power supply is connect by either using the top screw terminals or the top 2.1mm barrel plug connector. Each channel is fully isolated when powered by separate power supplies.

Modules come equipped with rear mounted DIN rail mounting brackets for attaching to standard 35mm DIN rail.  Optional DIN rail to 19 inch rack bracket available.

Users can build a system with standard DIN mounted power supplies or brick style supplies conveniently positioned.

The system is used with BA500WIN for operation, control, monitoring and data collection. Connection to the computer is accomplished by using a USB to Data BUS controller. Only 1 USB controller is required per system. The first module connects to the controller and the other modules connect to each other. The controller can be mounted to the side of a module as pictured or DIN rail mounted.

New Customers will receive a Network Controller (included) to communicate with all modules on the system.

Network Controller

Each system requires a network controller to interface the modules to a computer.  The module has a USB type B input and Modular cable output.  Each module has two Modular connectors to connect to the Network Controller and the next channel on the system.  Just one controller is required for any number of modules.  The controller can be mounted on DIN rail or used inline between cables.
