PRODUCT PERFORMANCE​

Adopts Triple Modular Redundancy (TMR) architecture design, three independent channels collect and process signals in parallel, automatically switch with fault tolerance in case of failure, ensuring uninterrupted signal acquisition and meeting SIL 3 safety level requirements​

16 independent digital input channels, supporting flexible configuration of dry contacts/wet contacts, can be directly connected to on-site sensors, limit switches and other equipment, adapting to multi-scenario signal acquisition needs​

1500VAC electrical isolation between channels and backplane, effectively resisting electromagnetic interference and ground loop interference in industrial sites, ensuring signal transmission integrity​

Wide-range 24VDC power supply design, withstanding 20.4-26.4VDC voltage fluctuations, adapting to complex industrial power grid environments, ensuring continuous and stable operation of the module​

Industrial-grade wide-temperature tolerance capability, can operate stably in the temperature range of -40℃ to 70℃ and non-condensing humidity environment of 5%-95%, adapting to extreme industrial scenarios​

Signal response time ≤1ms, quickly collecting on-site digital signals and transmitting them to the controller, ensuring real-time triggering of safety control commands​

Built-in multiple diagnostic functions such as channel short circuit, open circuit and power supply abnormality, fault information is fed back in real time through the controller, facilitating rapid problem location and reducing operation and maintenance costs​

Compatible with TRICON full-series controllers and standard racks, supporting hot swapping (requires system configuration support), facilitating system expansion and online maintenance​

Complies with ATEX Zone 2 and FM Class 1 Div 2 explosion-proof certifications, can be applied in flammable and explosive hazardous environments to ensure production safety​

Modular design and standardized interface, seamlessly integrated into Safety Instrumented Systems (SIS), improving the overall safety and reliability of the system​
