AI620 Analog input module S800 I/O series
AI620 is an analog input module launched by ABB, belonging to the S800 I/O series. It is mainly used for the acquisition and processing of analog signals in industrial automation systems. Here is its detailed information:
- Module Type: Analog input module (usually 8-channel or 16-channel, with 8-channel being more common)
- Input Signal Types: Supports standard analog signals, including 4-20mA, 0-20mA current signals, and 0-10V, ±10V voltage signals, etc.
- Resolution: 12 bits (some specifications may reach 16 bits, subject to model subdivision)
- Accuracy: ±0.1% of full scale (typical value at reference temperature), meeting regular industrial measurement requirements
- Isolation Mode: Electrical isolation between channels, optoelectronic isolation between the module and system bus, with isolation voltage ≥250V AC, effectively suppressing interference
- Update Rate: Approximately 250ms (per channel), suitable for medium-speed dynamic signal acquisition
- Operating Voltage: 24V DC (±10%)
- Power Consumption: Typical 3-4W
- Operating Temperature Range: -20°C to +60°C
- Storage Temperature Range: -40°C to +85°C
- Wide Signal Compatibility: Supports multiple current and voltage signals, allowing direct connection to sensors or transmitters without additional conversion modules, simplifying system design.
- Reliable Isolation and Anti-interference: Through channel isolation and filtering technology, it effectively resists electromagnetic interference (EMI) and radio frequency interference (RFI) in industrial environments, ensuring the stability of signal acquisition.
- Diagnostic Function: Equipped with basic self-diagnostic and channel fault detection capabilities, it can identify abnormalities such as wire breakage, short circuit, and over-range, and feed back status through the bus, facilitating quick troubleshooting.
- Flexible Configuration: The signal type and range of each channel can be independently set through system software to adapt to the output characteristics of different sensors.
- Easy Integration: Compatible with ABB's AC 800M and other control systems, supporting hot swapping, allowing online module replacement, and improving system maintainability.
- Mainly used for collecting analog signals converted from non-electrical physical quantities such as temperature, pressure, flow, and liquid level in industrial process control.
- Widely applied in automation systems of industries such as chemical engineering, electric power, metallurgy, water treatment, and manufacturing, providing on-site data for PLC or DCS to support the monitoring and regulation of production processes.
With stable performance, moderate accuracy, and good compatibility, this module is suitable for industrial scenarios requiring a balance between cost and reliability, making it a practical choice for regular analog signal acquisition.
