ABB DI801, article 3BSE020508R1, is a Digital Input Module for S800L I/O. Its exact model, article number and installed hardware revision must remain traceable to the operating system.
Engineering review should compare Input channels: 16; Input arrangement: 1 × 16 channels; Signal specification: 24 V DC; Signal type: Current sink; Rated isolation: 50 V. Confirm these published identifiers against the rack, termination, power, wiring and current project documentation.
For commissioning and maintenance, isolate the affected equipment, record the pre-change state, inspect labels and connectors, restore only approved settings and complete functional tests. MRO procurement should state the exact article number, condition, quantity, destination and revision restrictions.

S800L I/O is a legacy ABB automation platform. Confirm the complete installed configuration before replacement or migration.
Use the published thresholds: -3 to +5 V for state 0 and +15 to +30 V for state 1. Values in the undefined region require field-circuit investigation before commissioning.
Adjust the 2–32 ms delay only after reviewing contact bounce, pulse duration and process response. Record the approved value for every affected input group.
It defines the separation expected between field inputs and internal electronics. Inspect the ECZ base and insulation condition; perform only site-approved dielectric or insulation tests.
Reuse is acceptable only after terminal numbering, common conductors, polarity and conductor condition match the approved drawings and the replacement nameplate.
Allow for the documented maximum consumption of 0.2 A and maximum dissipation of 4.5 W, then include the module in the cabinet power and thermal calculation.
Typical causes include marginal field voltage, loose terminals, contact bounce, induced noise or an incorrect delay. Measure the signal at the ECZ terminal before replacing hardware.
Check 3BSE020508R1, connector and housing condition, terminal cleanliness, label traceability and channel response using a controlled 24 VDC test source.
Purchase against the full FPR number. 3BSE020508R1 is the 24 VDC selection; FPR3316101R0036 and FPR3316101R0034 identify different supply variants.
Send the model, complete part number, quantity, destination and nameplate photo. We will verify identification details before confirming availability and lead time.
