ADM-XX is a single-channel digital module. It is mainly used for vehicle crash test dummy data collection. It can also be used for high-speed synchronous collection of discrete sensor signals at industrial sites. The module's small size makes it easy to install close to the sensor and convert it into a digital signal; multiple ADM-XX can share an RS485 bus to transmit the signal in real time to the data recorder at the other end of the bus to achieve large-scale distributed data collection. This device is the core link in realizing distributed data collection, with low noise and simple wiring.
