ماژول ورودی آنالوگ ABB مدل AI880A، کد فنی 3BSE039293R1

The 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 AI880A complies with the NAMUR recommendation NE43, and supports configurable over- and under range limits.
