IO117: High-Impedance 16-bit Analog Input I/O Module

High-impedance 16-bit analog module with 32/16 multiplexed analog input channels and Simulink driver blocks

This I/O module offers a powerful combination of very high input impedance, a high analog input count, and small conversion and settling times. With high impedance and galvanic isolation, this I/O module is perfect for applications requiring very low leakage current (4 nA) such as direct battery measurement of battery management systems (BMS).

Reliability
Mean time between failures (MTBF) 552,000 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.
