ABB FI820F Serial Interface Module

Description

The ABB FI820F Serial Interface Module is a high-performance, high-reliability serial input/output fieldbus module designed for demanding industrial environments. It features 2 configurable serial interfaces with maximum transmission speeds up to 38.4 KBaud, supporting selectable physical interfaces including RS485, RS422, and RS232. All interfaces are electrically isolated to ensure signal transmission safety and stability, and the module supports redundant operation with a second AC 800F system, allowing hot swap during runtime for uninterrupted performance. Equipped with 8 input channels that accept 0-30V DC voltage signals and output 0-20mA DC current signals, it offers versatile I/O capabilities. It supports a wide range of serial fieldbus protocols, with MODBUS as the standard option, and is compatible with protocols like PROFIBUS and HART. Operating within a temperature range of -40 degrees Celsius to 70 degrees Celsius, it has compact dimensions: 200mm×100mm×50mm overall, with net measurements of 125mm depth, 155mm height, 28mm width, and a net weight of 0.145 kg. Ideal for industrial automation control systems, it is commonly used for expansion communication with ABB AC 800F controllers, enabling multi-loop temperature control, equipment linkage control, and reliable data communication when paired with configuration software.
