Honeywell FC-TCNT11 redundant circuit board

Honeywell FC-TCNT11 redundant circuit board

 Introduction

Honeywell FC-TCNT11 redundant circuit board

1. Adapt to the Safety Manager SC S300 safety instrumented system to complete redundant data exchange of the controller

2. Dual link hardware architecture to achieve real-time data synchronization between the primary and backup controllers

3. Fault triggers undisturbed automatic switching, and the safety logic executes continuously without interruption

4. Possess SIL3 safety level and meet the requirements of industrial safety instrument applications

5.24VDC industrial standard power supply, compatible with SIS cabinet power supply circuit

6. Hardware full chain self diagnosis, real-time identification of communication and hardware abnormalities

7. Support module hot plugging, online maintenance without stopping safety interlock

8. Fault safety failure design, hardware abnormalities automatically enter a safe state

9. Panel status indicator light, visually viewing the working status of redundant links

10. Electrical isolation treatment to resist on-site electromagnetic interference and avoid misoperation

11. Wide temperature working range, suitable for harsh working conditions of high and low temperatures in cabinets

12. Complete event log storage, recording switches and faults for easy troubleshooting

13. Rack plug-in structure, directly assembled with S300 system rack

14. The board is resistant to vibration and impact, suitable for long-term continuous operation in factories

15. Compliant with industry standards related to functional safety of IEC61508

The Honeywell FC-TCNT11 redundant circuit board is a redundant communication core board for SIS safety systems, commonly used in emergency interlocking projects in the chemical, oil and gas, and power industries.
