B&R X67MM2436
2x outputs (H bridge) with PWM control and 24 to 38.5 VDC ±25% supply 3 A rated current (5 A max current) 15 Hz to 50 kHz frequency, 16-bit PWM resolution, 15-bit, + sign, minimum 10 ns Configurable dither 2x 3 inputs 24 V, can be configured as ABR Sink connection Integrated sensor supply with short circuit protection 1-wire connections 24 VDC and GND for encoder supply 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.
