SA-Command Link

The APEX Series Controllers offer an optional RS232 Amplifier/Shaker interface and a software command/status panel to operate UD’s newly enhanced SA and SAI Series amplifier/shaker systems. The SA-Command Link provides identical functionality as the standard SA Amplifier front panel switch buttons, LED status indicators and current/voltage meters. In addition, it provides a Power Save selection to automatically power down the UD SAI Amplifier/Shaker system after a test has finished or aborted, and current / voltage limits can be set to abort the test for added system / specimen protection.  Now the complete UD test system can be initiated, monitored, and controlled from one convenient location.
