The ABB AI820 is a 4-channel analog input module for the ABB Ability System 800xA. It is used to convert analog signals from sensors and other devices into digital signals that can be processed by the control system.

The AI820 can accept a variety of input signals, including:

·Voltage: ±10 V, ±5 V, 0 to 5 V
·Current: ±20 mA, 4 to 20 mA
·Thermocouple: J, K, T, E, N, R, S, B, W

Each channel of the AI820 has a 14-bit resolution and a sampling rate of up to 250 kHz. The module is also galvanically isolated, which means that the input and output circuits are electrically separated from each other. This helps to protect the control system from noise and interference.

The AI820 is a compact module that measures 127 mm x 51 mm x 127 mm. It is mounted on a DIN rail in the control cabinet.

The AI820 is a versatile analog input module that can be used in a variety of applications, including:

·Process control
·Building automation
·Power generation
·Renewable energy

Here are some additional details about the AI820:

·Input impedance: 250 Ω (current), 1 MΩ (voltage)
·Common mode voltage: 50 V
·Accuracy: ±0.1% of full scale
·Operating temperature range: -40 to +85 °C
·Storage temperature range: -40 to +100 °C
·Weight: 0.2 kg
