Keterangan
The ABB AI810 (3BSE008516R1) is a high-performance, 8-channel analog input module designed for the S800 I/O distributed control system. This module provides versatile signal processing, allowing each of its eight channels to be independently configured for current (0–20 mA, 4–20 mA) or voltage (0–10 V, 2–10 V) inputs. Engineered for demanding industrial environments, the AI810 includes 12-bit resolution and supports HART communication, ensuring transparent transmission of digital diagnostics alongside analog process values.
Features
- 8 single-ended, unipolar input channels.
- Independent channel configuration for voltage or current signals.
- Integrated HART communication support for intelligent field device integration.
- Enhanced protection with PTC current-limiting resistors on all inputs.
- Short-circuit protection against transmitter supply voltages up to 30 V DC.
- 12-bit analog-to-digital conversion accuracy.
- Electrical isolation of the 8-channel group from ground.
Applications
- Refinery and petrochemical process control for pressure, flow, and level monitoring.
- Turbine auxiliary system instrumentation, including lube oil and steam monitoring.
- Boiler combustion control and water level management.
- Renewable energy site management for hydraulic and pitch control systems.
