16-bit Analog Current Loop I/O Module

The IO116 I/O module is a 16-bit analog input and output module for current input or output applications with Simulink® driver blocks. The I/O module provides 16 single-ended voltage or 8 differential current analog input channels, and 4 simultaneously updated analog output channels. Furthermore, 16 TTL lines are available that can be configured as inputs or outputs in groups of eight lines.

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

Mean time between failures (MTBF)* 526,000 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.
