ABB AI561 Analog Input Module
Description
ABB AI561 Analog Input Module is a high-performance analog input module designed exclusively for the AC 800M high-end programmable logic controller system, used to collect analog signals from industrial field devices.
| Specification | Value |
|---|---|
| Number of Channels | 8 differential input channels |
| Supported Signal Types | Voltage (+/-10 V, 0-10 V, 0-5 V), current (0/4-20 mA), RTD (Pt100, Pt1000, Ni100, etc.), thermocouple (J, K, T, E, N, R, S, B types) |
| Resolution | 16 bits |
| Accuracy | Typical +/-0.1% full scale; +/-0.2 degrees Celsius in RTD/TC mode |
| Sampling Period | Minimum 10 ms per channel |
| Isolation Voltage | No less than 500 V AC between channels and between channels and backplane |
| Operating Temperature | 0 to 60 degrees Celsius |
| Certifications | CE, UL, cUL, ATEX |
Key Features:
- Each channel can be independently configured without jumpers or hardware changes, maximizing engineering flexibility
- Built-in open-circuit detection function identifies sensor wire break faults and reports to the CPU for predictive maintenance
- Electrical isolation between channels and between channels and backplane prevents ground loops, common-mode interference, and surges from damaging the PLC system
- Front-panel green “OK” LED and red “ERR” LED enable quick on-site diagnostic checks
- Configurable via ABB Control Builder M software, supporting automatic linearization, filter time settings, engineering unit conversion, and channel-level diagnostics
Applications:
- Power plant boiler temperature (thermocouple) and pressure (4-20 mA) monitoring
- Water treatment plant pH value (+/-10 V) and flow (4-20 mA) signal collection
- Chemical reactor multi-point temperature (Pt100) high-precision monitoring
- Oil and gas pipeline pressure and liquid level redundant measurement
