TRICONEX AI3351S2 Analysis Input Module  

TRICONEX AI3351S2 belongs to the Tricon TMR triple redundant 32 channel analog input module and is a spare part for SIS safety instrumented system maintenance.
1.32-channel 4-20mA analog differential input, collecting transmitter process signals
2. TMR three out of two redundant architecture, with uninterrupted data collection for single point failures
3. Channel and backplane bus isolation to suppress on-site electromagnetic interference
4. Built in disconnection and short circuit diagnosis, real-time monitoring of circuit status
5. High speed ADC sampling, 10ms full channel refresh cycle
6. S2 hardware version, with stronger noise resistance and faster self checking speed
7. Support hot swapping, shutdown replacement to shorten maintenance time

8. Panel LED indicator light, quickly locate module and channel faults
9. Data exchange between backplane bus and Tricon main controller
10. DC24V backplane power supply, low module power consumption
11. Working temperature -40 ℃~+70 ℃, suitable for chemical cabinets in power plants
IEC61508 SIL3 safety certification meets ESD safety requirements
13. Three anti coating on the board, anti vibration, suitable for long-term continuous operation
14. Replacement and repair of the original AI3351S2 module malfunction
15. Spare parts reserve for SIS safety interlock system in petrochemical and power plants
This AI3351S2 is a Tricon high-density analog acquisition card used for collecting pressure, flow, and liquid level signals in high-risk processes.
