IO142: Fast sampling 16-bit analog I/O module for Simulink

IO142: Fast Sampling 16-bit Analog I/O Module

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

The IO142 I/O module is a fast sampling, 16-bit analog input and output module with Simulink^® driver blocks.

The I/O module provides 32 single-ended or 16 differential analog input channels, and 8 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^®.

¹ Actual settling time of the output may vary due to voltage/current output magnitude changes

² 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.
