National Instruments 783285-01 C Series Motor Drive Module.

The part number 783285-01 from National Instruments is the identifying part number for the NI-9503 C Series Motor Drive Module. This C series module is designed for use with 2-phase hybrid stepper motors in either bipolar or unipolar winding configurations. It is compatible with the CompactRio system, offering advanced motion control capabilities suitable for various industrial applications. This stepper motor drive offers a motor DC power supply of +9 to +30 VDC with a minimum phase inductance of 1 mH and maximum inductance of 20 mH. With the phase inductance feature, this module can maintain better performance and prevent troubleshooting with the driver such as thermal dissipation. 

The 783285-01 motor drive features Pulse Width Modulation (PWM) with a 20 kHz PWM frequency. This excellent feature allows this C series motor drive to regulate voltage and current levels supplied to the motor, enabling precise control of motor speed and torque. The high-frequency level that this module offers is particularly important for minimizing noise levels, hence making it suitable for environments requiring smooth and precise operations.

To make this motor drive functional, it needs to draw power from the PXI chassis of 500 mW maximum at active mode and 2.5 mW maximum at sleep mode. In terms of thermal dissipation, 1.5 W of power is dissipated at active mode and 2.5 mW maximum at sleep mode. For connectivity, this module offers screw terminal wiring of gauge 12 to 24 with 10 mm (0.39 in.) of insulation stripped from the end. It weighs 144 g (5.1 oz).

The motor drive module is required to be operated at an ambient temperature of -40 to 70 degrees Celsius and a storage temperature of -40 to 85 degrees Celsius with a relative operating humidity of 10 to 90% RH, noncondensing, and storage humidity of 5 to 95% RH, non-condensing. It has an ingress protection rating of IP40 thus preventing entry of insects and damage by tools and wiring. It is designed to be mounted at a maximum height of 2000 meters and has a pollution degree of 2 specifically designed for indoor use only where non-conductive pollution occurs.
