A&D Weighing RA30-112
Remote Control Module, 30V Maximum
RA30112
RA30-112
The A&D Weighing RA30-112 Remote Control Module is for use with the Omniace RA3100 Data Acquisition System. It includes three major types of functions: the remote function, carrier function for the AC strain module, and waveform confirmation output for the voltage input module.
- Start/stop, mark printing, and paper feed
- External sampling by external signal
- External trigger signal input and output
- Bridge power supply to 2ch AC strain module
