IO206: Digital Input Module with 32 Channels

Parallel digital input module with 32 channels of 12V or 24V inputs

This I/O module is a dedicated digital I/O module providing 32 channels of 12V or 24V inputs. The inputs are galvanically isolated by opto-couplers. All channels have a common freely programmable debounce time.

The following variants are available: the IO206 with 24V inputs, the IO206-12V with 12V inputs, and the IO206-8V with 8V inputs.

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.
