ABB AI890 3BSC690071R1 Analog Input Module
Manufacturer: ABB
Product Number: AI890 (3BSC690071R1)
Category: Analog Input Module with Intrinsic Safety
Number of Channels: 8
Input Signal Types: 4-20 mA (HART pass-through)
Resolution: 16 bits
Accuracy: ±0.1% of full scale
Isolation: Channel-to-channel and channel-to-backplane
Hazardous Area Rating: Intrinsic Safety (IS) for Zone 0/1
Product Description
The ABB AI890 3BSC690071R1 Analog Input Module is an industrial automation device designed for hazardous areas, featuring Intrinsic Safety (IS) protection on each channel. It allows direct connection to process equipment in Zone 0/1 without additional external protection devices. The module offers 8 single-ended unipolar input channels, supporting 0~20 mA and 4~20 mA current signals, and is capable of powering and monitoring two-wire transmitters. With groupwise isolation and robust design, it ensures high reliability and safety in complex industrial environments.
Key Features
- Intrinsic Safety Design: Each channel includes IS protection, enabling direct connection to Zone 0/1 devices (ATEX/IECEx certified).
- Multi-Channel Input: 8 independent channels for 0~20 mA and 4~20 mA current signals.
- Transmitter Power Supply: Each channel provides 15 V/20 mA to power Ex-certified two-wire transmitters.
- Overcurrent Protection: Current limited to 23 mA for safe operation under overload conditions.
- Fast Response: Update cycle of 5 ms for real-time monitoring and control.
- Compact Design: Lightweight and small dimensions for easy installation and integration.
