This motor bridge module is used to control 2 DC motors with a nominal voltage of 24 to 38.5 VDC ±25% at a nominal current up to 3 A. The module can be reconfigured and used in current controller mode for controlling inductive loads. The module is also equipped with 6 digital inputs, which can be used as incremental counters. Each motor is controlled with a full-bridge (H-bridge). This enables the motors to be moved in both directions.
