The ABB DI890 (Part Number: 3BSC690073R1) is an 8-channel digital input module within the S800 I/O family,
engineered for safe and reliable operation in hazardous environments.
It is particularly suited for industries such as oil and gas, chemical processing, and marine operations where intrinsic safety is paramount.
Intrinsic Safety: Each of the 8 input channels includes built-in intrinsic safety barriers, allowing direct connection to field devices in hazardous areas (e.g., ATEX/IECEx Zone 2 with interface to Zone 0) without the need for additional external safety components.
Signal Compatibility: Supports NAMUR proximity sensors and voltage-free (dry) contacts. NAMUR inputs enable line fault detection without extra components, while voltage-free contacts require external resistors for fault detection.
Galvanic Isolation: Each channel is galvanically isolated from the power supply, ground, and other channels, enhancing safety and reducing interference.
Diagnostics and Indicators: Equipped with front-facing LEDs indicating module status—Fault (Red), Run (Green), and Warning (Yellow)—along with individual channel status indicators. It also features internal process supply and loop supervision for comprehensive diagnostics.
Protective Features: Includes short-circuit protection to ground and 30 V, over-voltage, and over-temperature protection, ensuring robust operation under various conditions.
