Basic Product Identification
Model & Article Number: Model DI820, article number 3BSE008512R1.
Product Category: Digital input module, part of ABB’s Compact Product Suite, designed for the S800
mechanical platform.
Core Purpose: Used to collect 120 V AC/110 V DC digital signals from field devices in industrial
control systems.
Core Functional Characteristics
Channel Configuration: 8 digital input channels, with current sinking signal type.
Isolation Performance: Channels are individually isolated, ensuring no cross-interference between
signals.
Voltage Supervision: Channel 1 can supervise the power supply of channels 2–4; channel 8 can
supervise channels 5–7. If the supervision voltage disappears, a warning signal is triggered (Warning
LED lights up) and can be read via ModuleBus.
Signal Processing: Equipped with EMC protection components and current limiting components;
supports selectable digital filter times (2/4/8/16 ms) and analog filtering (On/Off delay 5/18 ms) to
enhance signal stability.
Status Indication: Front-panel LEDs include Fault (F), Run (R), Warning (W), and Channel 1–8 status
indicators for intuitive on-site monitoring.
Key Limitations: No HART protocol support, no SOE (Sequence of Events) function, no redundancy
design, no high integrity or intrinsic safety features.
