1.Product Overview
ABB AO820 is a high-performance analog output module launched by ABB,which is the core component of its automated control systems(such as ABB 800xA,AC500 series or industrial IT solutions).This module is designed to convert the digital signals generated by the control system into analog signals(such as voltage and current)required by the industrial site to drive actuators(such as valves,inverters,regulators,etc.),and is widely used in process control,energy management,intelligent manufacturing and environmental monitoring.
2.Core features
Multi-channel high-precision output
Number of channels:Usually 8 independent analog output channels are supported(some models may be extended to 16 channels).
Output type:Can be configured as a voltage(such as±10V,0-10V)or current(such as 0-20mA,4-20mA)signal to meet the needs of different actuators.
Resolution:16-bit(some models support 24-bit),ensuring smoothness and accuracy of the output signal.
Accuracy:±0.1%FS(full scale),suitable for high-precision control scenarios.
Industrial-grade reliability design
Operating temperature range:-20℃to+70℃(extended models support-40℃to+85℃),adapting to extreme environments.
Protection level:IP20(installed in the cabinet),optional IP65 protective shell for outdoor or harsh scenarios.
Isolation protection:The isolation voltage between channels and channels and buses is up to 1500V AC to prevent signal interference and equipment damage.
Anti-interference capability:Built-in electromagnetic compatibility(EMC)filter,complies with IEC 61000-4 standard,effectively suppressing industrial noise.
Flexible communication and integration
Communication protocol:Supports PROFIBUS-DP,Modbus RTU/TCP,EtherCAT or ABB dedicated protocols(such as ABB Totalflow),and is seamlessly compatible with mainstream PLC/DCS systems.
Bus interface:Use standardized interfaces(such as RJ45 or D-sub)to simplify wiring and maintenance.
Hot-swap function:supports live plug-in and unplug to reduce system downtime.
Intelligent diagnosis and maintenance
Real-time monitoring:Independent status detection of each channel(such as disconnection,short circuit,overload),and alarms through LED indicators or control system.
Online calibration:Supports software remote calibration without manual potentiometer adjustment.
Self-diagnosis function:The module has built-in fault detection logic,which can record the last 100 event logs for easy fault tracing.
