Frequently Asked Questions

• Does the module support hot-swapping?

  The S800 I/O system supports hot-swapping. Refer to the system hardware manual for specific procedures to avoid triggering process alarms during replacement.

• How is the module isolated?

  The module features optical isolation between the field inputs and the system bus, plus independent isolation for the two input groups.

• What happens if the field supply voltage drops?

  The module includes integrated voltage supervision; it will detect a loss of supply voltage and report the fault condition via the ModuleBus to the controller.

• Can the DI810 be used for safety functions?

  The DI810 is a standard process I/O module. Consult local safety integrity specifications before using it for critical safety interlock applications.

• Is the input voltage range configurable?

  The input range is fixed for 24 VDC nominal signals; refer to the datasheet for specific ON/OFF threshold limits.

• What is the current draw per channel?

  The module draws approximately 6 mA per channel at 24 VDC nominal input voltage.

• How is fault detection executed?

  Faults are communicated automatically to the central controller through the ModuleBus interface for rapid localization by engineering staff.

• Does the module require periodic calibration?

  The digital input circuit is solid-state and does not require field calibration; however, periodic visual inspection of wiring and terminals is recommended.
