The A&D Weighing RA30-102 4-Channel Voltage Module is an input module capable of voltage measurement up to ±200V. It includes an analog filter for waveform observation. It is insulated between each channel and between input and output. This input module enables stress measurement using strain gauges as well as strain gauge transducers such as load cells, pressure transducers, and torque transducers. The AC bridge method can be used for measurement that is strong against external noise. Use the NDIS conversion cable (RA30-508) to connect the NDIS connector (NDIS4102) attached to the bridge box and strain gauge type transducer cables (sold separately). For AC bridge power supply, the RA30-112 remote control module is required (sold separately).

It has a sampling speed of 1MS/s and 16 bit A/D resolution. The RA30-102 input module is for use with the Omniace RA3100 Data Acquisition System which enables up to 9 modules to be installed. It enables accurate and long-term measurement of high-speed switching waveforms, even in severely noisy environments, in electric automobiles, electronic appliances, railroad cars, and solar power generation systems utilizing inverter control technology.
