ABB HAI805 Analog input module
The ABB HAI805 is an 8 – channel analog input module, belonging to the ABB Symphony Plus S+ I/O series. This module is specifically designed for industrial automation scenarios. It is used to measure and convert analog signals from field devices such as temperature sensors, pressure sensors, and flow sensors into digital signals that can be processed by a control system. Each channel of it is equipped with a dedicated HART modem, which can communicate with HART devices such as smart transmitters to configure and diagnose these devices. In industrial automation and control systems, it undertakes the task of reading the output signals of sensors or other continuously variable devices and converting analog signals into digital signals that can be understood and processed by the control system.
