Product Name
ABB Industrial Automation Series AIP830-111 High-Precision Analog Input Module
(The “AIP” in the model name stands for “Analog Input Precision,” indicating the module’s core function of acquiring and conditioning analog signals from field sensors (e.g., pressure, temperature, flow transmitters) with high accuracy. It is a key component of ABB’s 800xA Distributed Control System (DCS) and AC500 PLC ecosystems, tailored for process industries like oil & gas, chemicals, and power generation—where reliable, precise analog data is critical for process control and safety.)
2. Product Description
The AIP830-111 module serves as a “data gateway” between field analog sensors and ABB’s control systems, enabling real-time, high-fidelity acquisition of process parameters in demanding industrial environments. In an offshore oil platform’s crude oil separation process, for example, this module connects to 8 independent field devices: including differential pressure transmitters (measuring oil-water interface levels), temperature RTDs (monitoring separator vessel temperature), and flowmeters (tracking crude oil output). It receives weak analog signals (4-20mA DC or 0-10V DC) from these sensors, processes them via built-in noise filtering and signal amplification circuits, and transmits digitized data to the ABB 800xA DCS—ensuring the DCS has accurate, low-latency data to adjust separation vessel pressure, heating, and valve positions.
A standout feature of the AIP830-111 is its exceptional measurement precision and isolation. With 24-bit ADC resolution and a measurement accuracy of ±0.02% F.S. (at 25°C), it can detect minute signal variations—such as a 0.01mA change in a pressure transmitter’s output, which corresponds to a 0.05% shift in crude oil level. This precision prevents overfilling or underfilling of the separation vessel, avoiding product waste or equipment damage. Additionally, the module incorporates 3-way electrical isolation (input-output-power, 2500V DC isolation voltage) and surge protection (IEC 61000-4-5, 2kV), which shields it from electromagnetic interference (EMI) from offshore platform motors, VFDs, and harsh weather-related voltage spikes—critical for maintaining signal integrity in marine environments.
