IO141: Fast Sampling 16-bit Analog I/O Module

Fast sampling 16-bit analog I/O module with Simulink driver blocks

The IO141 I/O module is a fast sampling, 16-bit analog input and output module with Simulink® driver blocks.
The I/O module provides 16 single-ended or 8 differential analog input channels, and 4 simultaneously updated analog output channels. Furthermore, 8 individually configurable TTL digital I/O lines are also available, which can generate interrupts triggered on the rising or falling edge, or both. Bouncing can be reduced by applying a configurable debounce filter. 
This I/O module is ideal for closed-loop controls and hardware-in-the-loop simulations using MATLAB® and Simulink

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.
