Description: The SD-220 is a chopper type full or half step driver for use with 4, 6, and 8 wire step motors. It has opto-isolated step, direction and Enable/Disable inputs that can either be driven directly by TTL gates or by open collector transistor outputs. The power supply voltage can range from 18 VDC to 40VDC and maybe unregulated. The motor phase current is adjustable up to 2 Amp. The SD-220 is encapsulated in a sturdy heat conductive aluminum case, making it suitable for use in a harsh environment.
