The MC-4SA is a multi-axis motor drive amplification system designed for use in systems where low power micro motors are required for a particular application.

The MC-4SA was designed for interfaceability to the National Instruments™ 7342 & 7344 series controllers. The MC-4SA interface connectors allow versatile connectivity based on the application and controller being used. All 4 axes may be accessed through a single cable.

Simple Connectivity

All of the difficult interfacing problems have been taken out of the hands of the user. For example; setup is simple; connect one end of the 68 conductor cable to the controller and the other to the MC-4SA, plug in your Mico-Mini™ stage and you are ready! No external power supply connections, no multi-wire motor connectons.

The MC-4SA also features a number of built-in protective devices and signal enhancement circuits such as;

  • Supply Rail Monitoring (SRM)
  • System status monitoring
  • Kickless Balanced Power Supply
  • Encoder conditioning
  • Reversible motor polarity

National Aperture, Inc. can provide custom electronic and mechanical design services in order to integrate the MC-4SA into your application.
