  • Product Details

The DO820 is a Digital Output (Relay NO) module designed for the S800 I/O system, offering 8 channels of 230 V a.c./d.c. relay outputs. This module provides isolated relay outputs with a range of features designed to ensure reliable and safe operation in industrial environments.

Key Features:

  • Relay Outputs: 8 channels for 230 V a.c./d.c. (5 – 250 V a.c./d.c.) with Normal Open (NO) contacts.
  • Current Handling: Each output channel can handle up to 3 A of continuous current.
  • Channel Isolation: Outputs are individually isolated, ensuring minimal interference and greater safety.
  • Status Indicators: Each output channel has an output status indicator LED to show the current state.
  • Error Handling: The module features output state protection (OSP) that sets outputs to a predetermined state upon error detection.
  • Relay Supply Supervision: The module includes a 24 V relay power converter monitor, which provides error signals if relay voltage is lost. This can be monitored via the ModuleBus, and the error status is indicated by a Warning LED.
