Stepping Motor Intelligent Motion Driver/Controller

ACS MCB-4B Controller

The ACS Scientific SMC-32A and SMC-32B  Serial Machine Controllers are simple and cost effective solutions for the stand-alone control of any stepping motor driven machine or experiment. SMC-32A/B is an integrated stepping motor controller/driver unit. It can drive and control any 4, 6, or 8 lead two/four phase stepping motor with continuous currents up to 3A (6A peak) at motor supply voltages up to 48VDC.

The SMC-32A is an addressable controller, controlled serially by a host computer via simple RS-232 communications.

The SMC-32B version has all the electronic characteristics and also functions as an independent intelligent controller with program stored in the controller’s nonvolatile memory
