The DAQ416 Data Acquisition System is a high performance, four-channel analog to digital board set. It was specifically developed for moderate-speed data acquisition from sensors such as Photodiodes and other analog devices. Up to 127 DAQ416 modules can be interfaced to a single RS232 interface using its networking capabilities. A single 9VDC input is provided to power the unit. The DAQ416 also offers many digital input and outputs on the same 26 pin connector used for analog signal sampling.
