DI890 3BSC690073R1| ABB | Digital Input Module
Description
The DI890 is an 8-channel digital input module designed for use in hazardous areas, featuring intrinsic safety protection on each channel. It supports NAMUR proximity sensors or volt-free contacts and includes galvanic isolation between channels, the power supply, and ground. The module can detect line faults without additional external components when using NAMUR sensors, while volt-free contacts require external resistors for state sensing. Power to the input stages is derived from the 24 V power supply connections. The DI890 is compatible with TU890 (Ex applications) and TU891 (non-Ex applications), enabling two-wire connections to process devices without additional terminals.
Features
- 8 Channels: With process voltage supervision
- Intrinsic Safety: Protection on each channel for hazardous area applications
- Galvanic Isolation: Channel-to-channel and to circuit common ground
- NAMUR Inputs: Supports NAMUR proximity sensors
- Line Fault Detection: For NAMUR sensors (no additional components needed)
- Output Status Indicators: LEDs for module status (Fault, Run, Warning) and channel status
- OSP Functionality: Sets outputs to a predetermined state upon error detection
- Protection: Short-circuit protection to ground and 30 V, over-voltage, and over-temperature protection
- Diagnostics LEDs: F(ault), R(un), W(arning), Channel 1-8 status
- Supervision: Internal process supply and loop supervision
