Simultaneous-Sampling 16-bit Analog I/O Module

The IO144 I/O module is a fast, simultaneous-sampling, 16-bit analog voltage/current output module, with digital I/O, and Simulink® driver blocks.

The I/O module provides eight single-ended analog output channels that can be updated individually or simultaneously. Individually configurable TTL digital I/O lines are also available.

This I/O module is ideal for closed-loop controls and hardware-in-the-loop simulations using MATLAB® and Simulink.

± 15kV ESD protection

Mean time between failures (MTBF)* 283,000 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.
