ABB DI890 Digital Input Module
The ABB DI890 (3BSC690073R1) is an 8-channel intrinsically safe digital input module, designed for direct connection to NAMUR sensors or volt-free contacts in hazardous areas without requiring external safety barriers.
Description
This compact digital input module provides individual galvanic isolation per channel, supports intrinsic safety applications, and integrates directly with S800 I/O systems, ideal for use with TU890/TU891 MTUs in Ex and non-Ex environments.
Features
- 8 intrinsically safe input channels
- Supports NAMUR sensors and volt-free contacts
- No external components required for line fault detection with NAMUR sensors
- Features short-circuit, over-voltage, and over-temperature protection
- Includes LED indicators for real-time status monitoring
- Complies with ISA-S71.04: G3 corrosion protection standard
- Certified for ATEX/IECEx Zone 2 and cFMus Class I Div 2/Zone 2
Technical Specifications
- Input type: NAMUR or voltage-free contact
- Isolation: Individual channel-to-channel and ground isolation
- Filter times: Selectable at 2, 4, 8, or 16 ms (analog filter: 1 ms)
- Power dissipation: 1.4 W
- Current consumption: Up to 150 mA @ +5 V Modulebus
- External current draw: Up to 70 mA @ 24 V
-
Dimensions:
- Width: 45 mm
- Height: 119 mm
- Depth: 102 mm (111 mm with connector)
- Weight: 0.2 kg
- Operating temperature: 0 to +55 °C
- Certifications: CE, ATEX, cFMus, RoHS compliant
