More Information

Overview Manuals Specifications 48 V Wiring Filter Setup Diagnostics

Features:

  • 48 V DC input service: Sixteen current-sinking channels use the ABB-documented thresholds.
  • Two supervised groups: Each group of eight has separate process-voltage monitoring.
  • Selectable filtering: Four digital filter times are available for contact behavior.

This model is defined by its 48 V DC input service and must not be confused with the 24 V DI810 configuration.

It reports field states and group supply status through the S800 ModuleBus while providing front channel indication.

Confirm the field voltage, thresholds, input-group wiring, supervision inputs, filter time, MTU, and keying before installation.

Availability is subject to Apter Power inventory and sourcing confirmation.

Field-voltage preparation

  • Supply class: Verify the approved 48 V DC field source.
  • Thresholds: Check the field device states against ABB on/off ranges.
  • Polarity: Confirm current-sinking wiring before energizing.
  • Isolation groups: Keep the two eight-channel groups correctly separated.

Contact-response checks

  • 2 ms: Use only when the approved signal requires the fastest listed filter.
  • 4 or 8 ms: Match the engineering database and contact behavior.
  • 16 ms: Use the longer listed filter only with the approved timing.
  • Validation: Test real transitions and alarms after configuration.

48 V input troubleshooting

  • No recognition: Measure field voltage and compare it with the documented thresholds.
  • Group warning: Check the matching process-voltage supervision input.
  • Chatter: Review filter time, contact quality, shielding, and grounding.
  • Wrong logic: Verify sinking signal polarity and channel mapping.
Description
DI811 3BSE008552R1 is an ABB S800 I/O digital input module with sixteen 48 V DC current-sinking channels arranged in two isolated groups of eight.

DI811 3BSE008552R1 provides input status indication and one process-voltage supervision input per group. Its selectable digital filtering supports the ABB-documented 48 V signal ranges.

Before installing DI811 3BSE008552R1, confirm the 48 V field supply, on/off thresholds, group supervision, filter setting, compatible MTU, keying code, and complete article number.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
When should DI811 be selected for an existing digital input panel?
Check the full article number and verify the approved 48 V DC current-sinking design; do not rely on module appearance.
Which MTU and field-supply details must be verified before ordering DI811?
Provide the full MTU label, terminal arrangement, mechanical keys, field-power groups, and cabinet orientation.
What project information should accompany a DI811 quotation request?
Send the module nameplate, 48 V supply details, MTU, quantity, required condition, channel use, and delivery destination.
What wiring checks are required before energizing DI811 input groups?
Verify supply voltage, polarity, group returns, supervision inputs, channel tags, isolation, and cabinet grounding.
What should be checked when DI811 does not recognize a field signal?
Measure the signal at the terminal, compare it with ABB thresholds, then check polarity, return, filtering, and channel diagnostics.
How should DI811 input filtering be tested during commissioning?
Match the approved filter value, operate the real field contact, and confirm response time and freedom from chatter.
What engineering review is required before replacing DI810 with DI811?
No. Compare 48 V versus 24 V service, thresholds, keying, MTU, wiring, group power, and software configuration.
