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).

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.
