IO204: Digital I/O Module

Parallel digital I/O module with 16 channels of 12V or 24V inputs and 16 channels of 6 to 48V outputs

This I/O module is a dedicated digital I/O module providing 16 channels of 12V or 24V inputs and 16 channels of 6 to 48V outputs. All channels are galvanically isolated by opto-couplers, and have a common freely programmable debounce time. All outputs are protected against short-circuit and thermal overload and can output up to 0.5A per channel.

It is available with either 24V or 12V inputs, and either high or low-side switching on the outputs.

Digital Inputs

  • 16 x 24V channels (IO204)
    16 x 12V channels (IO204-12V)
  • Galvanically isolated (optical)
  • Programmable debounce circuit (7us to 440ms in steps of 7us)

Digital Outputs

  • 16 channels, 6 to 48V (from an external source)
  • Maximum output current 0.5A continuous per channel (at 24V)
  • Galvanically isolated (optical)
  • High-side or low-side switches (order options)

The IO204 is available with either 16 galvanically isolated high-side (default) or low-side switch outputs resulting in the wiring below:

Output wiring high-side switch

Output wiring low-side switch

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.
