T8111C是一款擴(kuò)展器，具體地說(shuō)，它是一個(gè)TMR（三重模塊化冗余）冗余處理器模塊。這款擴(kuò)展器具有hft TMR架構(gòu)的容錯(cuò)能力，意味著它采用了三重模塊化冗余設(shè)計(jì)，通過(guò)三個(gè)相同的處理器不斷對(duì)正確的輸出進(jìn)行投票，從而提供高可用性和可靠性。

冗余處理器模塊廣泛應(yīng)用于需要高可靠性和容錯(cuò)能力的領(lǐng)域，如航空航天、軌道交通、工業(yè)自動(dòng)化等。在這些領(lǐng)域中，系統(tǒng)的故障可能導(dǎo)致嚴(yán)重的后果，甚至可能危及人們的生命安全。因此，采用冗余處理器模塊可以大大提高系統(tǒng)的穩(wěn)定性和可靠性，減少系統(tǒng)故障的風(fēng)險(xiǎn)。

如果一個(gè)處理器出現(xiàn)故障，另外兩個(gè)處理器可以繼續(xù)運(yùn)行而不會(huì)中斷。
此外，T8111C還通過(guò)了IEC 61508 SIL 3認(rèn)證，這是最高級(jí)別的功能安全認(rèn)證，表明它可以用于存在高受傷或死亡風(fēng)險(xiǎn)的安全關(guān)鍵應(yīng)用。它的溫度范圍擴(kuò)展至-40至+70°C，使其適合在惡劣環(huán)境中使用。并且，它本質(zhì)安全，適用于1級(jí)、1區(qū)和1區(qū)危險(xiǎn)場(chǎng)所，即使在有爆炸風(fēng)險(xiǎn)的環(huán)境中也可以使用。
總的來(lái)說(shuō)，T8111C是一款高可靠性、適用于惡劣環(huán)境和安全關(guān)鍵應(yīng)用的擴(kuò)展器模塊。

T8111C

The T8111C is an extender, specifically, it is a TMR (Triple Modular Redundancy) redundant processor module. The fault-tolerant hft TMR architecture of this extender means it features a triple modular redundancy design, with three identical processors constantly voting on the correct output, providing high availability and reliability. If one processor fails, the other two processors can continue to run without interruption.

Redundant processor modules are widely used in areas that require high reliability and fault tolerance, such as aerospace, rail transit, industrial automation, etc. In these fields, the failure of the system may lead to serious consequences, and may even endanger people’s lives. Therefore, the use of redundant processor modules can greatly improve the stability and reliability of the system and reduce the risk of system failure.
In addition, the T8111C is IEC 61508 SIL 3 certified, the highest level of functional safety certification, indicating that it can be used in safety-critical applications where there is a high risk of injury or death. Its temperature range extends from -40 to +70°C, making it suitable for use in harsh environments. Moreover, it is inherently safe, suitable for Class 1, Zone 1 and Zone 1 dangerous places, even in the environment with explosion risk can be used.
Overall, the T8111C is a highly reliable extender module for harsh environments and safety-critical applications.
