ABB 3BDH000031R1 FI 820F Fieldbus Module Serial

Scenarios requiring local data recording or remote firmware updates.

FI 810F 

Single channel design, lower cost, suitable for simple serial communication requirements.  

Small automation systems, such as single machine equipment control.

Application scenarios

manufacturing

Connect PLC with intelligent instruments (such as temperature controllers and pressure transmitters), collect process parameters in real-time and upload them to SCADA system.

In the automotive production line, control robots communicate with welding guns, fixtures, and other equipment through Modbus RTU protocol to achieve precise motion coordination.

Energy and Electricity:

In a photovoltaic power station, the operational data of the inverter (such as voltage, current, and power) is collected and summarized to the central controller through the RS-485 bus.

In the substation, connect smart meters and relay protection devices to achieve remote monitoring and fault diagnosis of power parameters.

Process control:

In the chemical reaction kettle, the opening of the regulating valve is controlled through Modbus protocol to regulate the material flow rate and achieve closed-loop control.

In sewage treatment plants, water quality analyzers (such as pH meters and flow meters) are connected to monitor treatment process parameters in real-time and adjust the operation status of dosing pumps.

Building automation:

In intelligent buildings, the serial data of integrated elevator controllers and air conditioning units is converted into BACnet protocol through FI 820F and connected to the building management system (BMS).
