CI626A 3BSE005029R1

1. AF100 coaxial bus main station communication
As a dedicated master card for AC110/AC160 controllers connected to the 75 Ω coaxial AF100 bus, it enables real-time data exchange between the controller and S800/S600 remote IO stations, as well as on-site instruments
Transmission of switch quantity, analog quantity, SOE event timing message, control output instruction
The bus topology supports bus type and tree type, with a maximum of all AF100 field nodes mounted on a single bus
2. Medium redundancy hot backup (enhanced in version A)
Dual BNC channels support coaxial bus redundancy, automatically switching without disturbance when one cable is disconnected/short circuited, without interrupting the unit control logic; Compared to the first generation CI626, version A has optimized redundant switching response speed and reduced switching jitter.
3. Optimization of anti-interference signal modulation
CI626A has upgraded its coaxial modulation and demodulation circuit, which enhances signal stability in strong electromagnetic environments such as power plant frequency converters and high-power motors. It is less prone to communication packet loss and numerical drift when laid over long distances in the factory area.
4. Full link fault diagnosis
Real time monitoring of coaxial cable breakage, impedance mismatch, offline bus nodes, and short circuits; Upload the fault code to the controller, the upper computer will pop up an alarm, and quickly locate the line fault.
5. Global time synchronization of the system
It can serve as the AF100 bus time master, issuing a unified time scale to all downstream IO stations to ensure the accuracy of SOE event timing for the entire plant and adapt to the fault tracing needs of power plants.
