Product Overview – ABB DI810‑1 (3BSE008509R1)
Brand: ABB
Series: S800 I/O family
The ABB DI810‑1 is an industrial-grade digital input module tailored for integration with ABB’s control systems. It processes up to sixteen 24 V DC digital input signals, arranged across two isolated groups of eight channels each. The module supports both dry contacts and 24 V DC current‑sinking inputs, offering reliable signal detection with configurable filters and robust diagnostics.
Applications span across manufacturing, process control, building automation, and infrastructure systems—collecting signals from sensors, switches, and buttons for PLC or DCS interpretation.

10 FAQs – Q&A Format
-
Q: What does the DI810‑1 module do?
A: It reads up to sixteen discrete input signals (24 V DC or dry contacts) and conveys them to the control system. -
Q: Can it handle both dry-contact and voltage inputs?
A: Yes. It supports both dry contacts and 24 V DC current-sinking inputs. -
Q: How are signals filtered?
A: Users can select input filter times of 2, 4, 8, or 16 ms to suit different signal characteristics. -
Q: What diagnostics are built-in?
A: The module tracks voltage thresholds, reports ON/OFF states, and provides LED status and fault detection. -
Q: How well isolated are the groups?
A: There is galvanic isolation between two groups (8 channels each) and tested insulation up to 500 V. -
Q: How hardy is it in extreme environments?
A: It operates from about 0 °C to +55 °C (some sources suggest –40 °C to +70 °C), with robust IP20-level protection. -
Q: Can it be installed while a system is running?
A: Yes — it supports hot-swap use with compatible termination units. -
