ABB DI802 8-Channel 120V AC/DC Digital Input Module

ABB DI802 Digital Input Module: 8-Channel 120V AC/DC S800 I/O Solution

The DI802 is a compact 8-channel digital input module designed for S800 I/O systems, supporting 120V AC/DC current-sinking inputs. With individual channel isolation, voltage supervision, and integrated EMC protection, it delivers reliable performance for industrial automation applications.

Key Features

• 8 independent channels for 120V AC (77-130V) / 110V DC (75-145V) current-sinking inputs.
• Individually isolated channels to enhance noise immunity and system safety.
• Voltage supervision of field input power for proactive fault detection.
• LED indicators for real-time input status monitoring (per channel) and module health.
• Selectable digital filter times (2/4/8/16 ms) and analog filtering (5/18 ms on/off delay).
• Detachable process connectors for quick wiring and maintenance.
