3BSE052604R2 | AI815-eA | ABB System 800xA HART Input

Product Description

The AI815-eA (Part Number: 3BSE052604R2) is a versatile 8-channel analog input module designed for the ABB AC 800M controller and the System 800xA architecture. This module is specifically engineered to acquire high-precision analog signals from sensors and transmitters in demanding process automation environments. A key technical advantage of the AI815-eA (3BSE052604R2) is its native distribution of HART-compatible transmitter supply to each channel, which significantly simplifies the wiring for 2-wire or 3-wire transmitters.

Functionality within the AI815-eA (Model: AI815-eA) is highly flexible; while each module must be dedicated to either voltage or current signals (mixing types on a single unit is not supported), it provides robust circuit protection. The inputs are designed to withstand overvoltage or undervoltage of at least 11V DC. Furthermore, the AI815-eA (3BSE052604R2) includes supervised and current-limited transmitter power, ensuring that field faults do not compromise the integrity of the controller's I/O backplane.
