ABB AI880/AI880A High Integrity Analog Input Module product specification
The AI880/AI880A High Integrity Analog Input Module is designed for single and redundant configuration. The module has 8 current input channels.
The input resistance is 250 ohm. The module distributes the external transmitter supply to each channel. This adds a simple connection to distribute the supply to 2- or 3-wire transmitters. The transmitter power is supervised and current limited. All eight channels are isolated from the ModuleBus in one group. Power to the Module is generated from the 24 V on the ModuleBus.
The AI880/AI880A complies with the NAMUR recommendation NE43, and supports configurable over- and under range limits.
As AI880/AI880A needs external shunt sticks, the MTUs TU844, TU845 or TU854 is required for redundant configurations and TU834 for single configurations. AI880A has HART pass-through functionality. Only point-to-point communication is supported. Sensors should be for 24 V power supply if it should be powered from the module. Shielded field cables are required for process connections.
