This interface board uses the popular LMD18200 h-bridge.  An ideal servo drive for DC motors rated up to 3A continuous (6A peak).  A current sense pin allows the ATD circuitry of the servo module to detect high inertial loading or stall.
The DC supply voltage must be 12V or greater to operate the h-bridge and less than 26V to stay within the max Vin limit of the voltage regulator that powers the servo module, encoder and limit switches.  Jumper and user configurable settings are indicated in the schematic.  Typical optical limit and deadman switching are described in this schematic.
