Functional features

1. High-precision multi-channel acquisition: ABB AI830A module synchronously acquires RTD signals through 8 independent channels, 14-bit resolution combined with real-time linearization processing to ensure that the temperature monitoring error is ≤±0.1℃, meeting the accuracy requirements of demanding industrial scenarios

2. Dynamic anti-interference capability: Built-in programmable power frequency filter (50Hz/60Hz notch) effectively suppresses electromagnetic interference; IP65 protective housing design enables ABB AI830A to operate stably in dusty, humid or corrosive environments (such as chemical workshops).

3. Intelligent diagnosis and safety protection: Integrated open circuit/short circuit monitoring and input grounding detection functions, real-time diagnosis of sensor status; modular design supports hot-swap maintenance, greatly reducing the risk of system downtime.

4. Flexible configuration and industrial compatibility: Each channel can be independently configured with sensor type (Pt100/Ni120, etc.), directly output ℃/℉ unit value; seamlessly compatible with mainstream control systems such as ABB Advant OCS, 800xA, etc., simplifying integration complexity

Typical scenarios

Real-time monitoring of chemical reactor temperature (such as Pt100 monitoring ±1℃ fluctuation)

Generator winding temperature acquisition (anti-electromagnetic interference design ensures reliable data)

Pharmaceutical sterilization process compliance records (IP65 protection adapts to clean area environment)
