The Battery Metric™ 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 35 x 7.5 mm 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.

Each module includes:

● 3 current ranges and 16 voltage ranges for precision.
● 12 bit A/D & 12 bit D/A for 0.25% full scale accuracy.
● Short circuit, reverse polarity and overload protection.
● 8 lower screw terminals to connect battery, temperature probe or optional I/O lines.
● Four wire or two wire battery connection.
● LED status and power indicators. Vector control button.
