A multi port serial card is a device that can allocate multiple serial/parallel ports for terminal connections, and each terminal can communicate with the host through it. The serial port mentioned here usually refers to serial communication interfaces such as RS232, RS422, and RS485, while the parallel port refers to the PARALLE PORT, a 25 pin parallel interface, also known as a printer interface.

FBM202 P0926EQ Discrete I/O module
FBM202 P0926EQ is a specific model of serial interface component commonly used in automation control systems. It provides 8 thermal resistance (RTD) input channels, each of which can accept 2-wire or 3-wire RTD sensor inputs within the resistance range of 0 to 320 ohms.
The basic composition of FBM202 P0926EQ multi port serial card:
Hardware structure:
Shell:
FBM202 P0926EQ adopts a dense design and a sturdy pressed aluminum casing, providing physical protection for electronic circuits.
Installation method:
Supports DIN rail or rack installation, making it easy for users to deploy according to their actual needs.
Number of ports:
Based on specific design and usage, FBM202 P0926EQ provides multiple serial ports (although the specific number is not explicitly mentioned in the reference article, a multi port serial card typically means it has more than one serial port).
Electrical characteristics:
Electrical isolation:
Each analog input is electrically isolated from other channels and ground to ensure the safety and accuracy of data.
Input channel:
FBM202 P0926EQ provides multiple thermal resistance (RTD) input channels, each of which can accept 2-wire or 3-wire RTD sensor inputs within the resistance range of 0 to 320 ohms.
Scanning and filtering:
Scanning frequency:
Using Sigma Delta data conversion, scanning every 25 milliseconds to ensure fast response.
Filtering function:
The configurable moving average filter can remove any process noise and power line frequency interference, improving data quality.
Communication interface:
Fieldbus communication:
The communication between FBM202 P0926EQ and the main control station is achieved through an optional redundant 10Mbps Ethernet based fieldbus.
Communication protocol conversion:
The fieldbus communication component FCM is used for the conversion between the communication protocol used by FBM and the communication protocol used by Ethernet fieldbus.
Redundant design:
The communication information received by FBM202 P0926EQ comes from any path (A or B) on the redundant Ethernet fieldbus, ensuring the reliability and stability of communication.
Substrate installation:
The FBM202 P0926EQ component is installed on a DIN mounting substrate, which can accommodate multiple fieldbus components.
The working principle of FBM202 P0926EQ multi port serial card:
Signal input and isolation:
FBM202 P0926EQ provides multiple (usually 8) thermal resistance (RTD) input channels.
Each channel can accept 2-wire or 3-wire RTD sensor inputs within the resistance range of 0 to 320 ohms.
Each analog input is electrically isolated from other channels and ground to ensure data independence and safety.
Signal processing:
Use Sigma Delta data conversion technology to convert signals from RTD sensors.
Scan the input channel every 25 milliseconds to ensure fast response and real-time performance.
A configurable moving average filter is used to remove any process noise and power line frequency interference to improve data accuracy.
Communication interface and protocol:
FBM202 P0926EQ communicates with the main control station through an optional redundant 10Mbps Ethernet based fieldbus.
The Fieldbus Communication Module (FCM) is used to convert between the communication protocol used by FBM and the communication protocol used by Ethernet fieldbus.
Support redundant communication paths (A or B), once a path fails or is switched by the system, components can continue to communicate through the active path to ensure system reliability.
Substrate installation and connection:
FBM202 P0926EQ is installed on a DIN mounting substrate, which can accommodate multiple fieldbus components.
The substrate supports DIN rail installation or rack installation, making it convenient for users to deploy according to their actual needs.
The substrate is also equipped with redundant fieldbus connection sockets, independent DC sockets, and I/O cable sockets for easy connection and maintenance.
Fault diagnosis and status monitoring:
The light-emitting diode (LED) installed on the panel is used to indicate the working status of the fieldbus components, facilitating user fault diagnosis and status monitoring.
Maintenance and replacement:
FBM202 P0926EQ supports hot swapping function, which can be performed without interrupting system operation, improving system maintenance and reliability.
In summary, the FBM202 P0926EQ multi port serial card is an interface component designed specifically for automation control systems, providing 8 thermal resistance input channels, with characteristics such as electrical isolation, fast scanning, filtering, and reliable communication. Its design considers protection in harsh environments, supports redundant communication paths, and ensures data accuracy and communication stability. In addition, FBM202 P0926EQ also supports DIN rail or rack installation, making it convenient for users to deploy according to their actual needs.
