IO143: Simultaneous Sampling 16-bit Analog Output Module

Fast simultaneous sampling 16-bit analog voltage/current output module with Simulink driver blocks

As each analog output channel has its own dedicated D/A converter, signals are sampled simultaneously and the conversion time is constant. The I/O module can also be connected by trigger lines to additional I/O modules to synchronously sample and convert analog input or output channels across the different modules. This I/O module is ideal for closed-loop controls and HIL using MATLAB and Simulink.

± 15kV ESD protection

Mean time between failures (MTBF)* 356,000 hours
MTBF (Mean Time Between Failure) - MTBF values shown are based on calculation according to MIL-HDBK-217F and MIL-HDBK-217F Notice 2; Environment: GB 20°C. The MTBF calculation is based on component FIT rates provided by the component suppliers. If FIT rates are not available, MIL-HDBK-217F and MIL-HDBK-217F Notice 2 formulas are used for the FIT rate calculation.
