The DR-A8 is designed for data collection of dummies used in automobile crash tests. The sensor signals are digitally transformed through the ADM module, and the data is transferred to the DR-A8 for collection and recording. Since RS485 supports channel bus sharing (when collecting at 20kHz, each RS485 bus supports 12 signal collections), which greatly simplifies the internal wiring of the dummy. DR-A8 can provide 96 channels of signal acquisition, and with the dedicated UPS battery DR-A8-BAT, it is suitable for H3-50th, H3-5th, ES-2re, SID-2s and other dummy data acquisition (In-Dummy).
