Standard configuration basic IO: 8-channel digital input DI+6-channel digital output DO
IO Scalable: Through the FlexBus bus expansion module, it can expand up to 142 I/O points and adapt to complex production line interlocking logic CSDN ..
2kV electrical isolation design to resist strong electromagnetic interference in industrial sites
2. Program and Data Storage
Program storage: 8K step flash EPROM, program not lost in case of power failure
Data storage: 8K word data register, storing tension parameters, equipment operation curves, and fault records
3. Multi bus industrial communication
Support multi protocol docking with upper level DCS/PLC to achieve remote monitoring, parameter modification, and fault upload:
Profibus DP、Modbus RTU/TCP、RS232/RS485、 Ethernet IP communication
4. Special adaptation for tension control
High speed computation cycle, real-time processing of Presductor tension head signal
Automatic calculation of single roller tension, total tension, and differential tension, closed-loop control of magnetic powder clutch/brake
Built in complete fault self diagnosis: sensor disconnection, short circuit, module power supply abnormality, communication loss, onboard LED fault indicator light quickly locates faults
5. Industrial protection and environmental adaptation
Three anti moisture coating for circuit boards, suitable for high humidity production lines such as papermaking, thin films, metal foils, lithium battery electrodes, etc
Multiple electrical protections: input/output short circuit, overcurrent, undervoltage protection
