Description

AI820 ABB Controller module

Product Dimensions：

Product Description

The AI820 module provides 4 differential input channels. Unlike single-ended modules, its differential nature allows it to measure the voltage difference between two points, effectively canceling out common-mode noise that often plagues industrial settings.

Product Parameters

Below are the core technical parameters for the AI820:

Parameter Specification
Number of Channels 4 (Differential)
Resolution 14 bits (including sign)
Input Ranges ±10 V, 0..10 V, 0..5 V, ±5 V, 0..20 mA, 4..20 mA
Input Impedance >10 MΩ (Voltage), 250 Ω (Current)
Isolation Groupwise isolated from ground
Update Time 10 ms (at 50 Hz), 8.3 ms (at 60 Hz)
Power Dissipation Max 1.2 W

Key Advantages

  • High Noise Rejection: The differential inputs are excellent at filtering out electromagnetic interference (EMI).

  • Versatility: Supports both voltage and current signals, allowing you to standardize on one module type for various sensors.

  • Hot Swap Capability: Like most S800 modules, it can be replaced while the system is powered (under certain conditions), reducing downtime.

  • Diagnostic Features: Includes internal self-tests and reporting for “Module Error” or “Channel Error” states.

Important Precautions (Notes)

  1. Termination Units: The AI820 must be used with a compatible Module Termination Unit (MTU), such as the TU810, TU812, or TU830.

  2. Current Measurement: To measure current (mA), you generally need to use an external shunt or specific MTU wiring to convert the signal.

  3. Signal Grounding: Ensure that the common-mode voltage does not exceed the specified limits (typically ±15 V) to avoid inaccurate readings or hardware damage.

Product Applications

The AI820 is widely used in heavy industries where signal integrity is critical:

  • Oil & Gas: Monitoring pressure and temperature sensors over long cable runs.

  • Power Generation: Interfacing with turbine control systems.

  • Chemical Processing: Handling sensitive 4-20 mA loops from flow meters and pH analyzers.

  • Water Treatment: Managing remote telemetry units in electrically “noisy” pump stations.
