西門子緊湊型CPU的優(yōu)點(diǎn)包括： 1. 尺寸小：西門子緊湊型CPU相對(duì)于傳統(tǒng)的大型CPU來(lái)說(shuō)，尺寸更小，占據(jù)空間更少。這使得它們可以更容易地集成到緊湊的設(shè)備和系統(tǒng)中。 2. 低功耗：緊湊型CPU通常具有較低的功耗，這意味著它們?cè)谶\(yùn)行時(shí)消耗的能量更少。這對(duì)于需要長(zhǎng)時(shí)間運(yùn)行或依賴電池供電的設(shè)備和系統(tǒng)來(lái)說(shuō)重要。 3. 高性能：盡管緊湊型CPU尺寸小且功耗低，但它們通常具有相當(dāng)高的性能。這使得它們適合于需要高性能的應(yīng)用，如工業(yè)自動(dòng)化、機(jī)器人技術(shù)和物聯(lián)網(wǎng)等。 4. 可靠性高：西門子作為一家的工業(yè)自動(dòng)化和控制解決方案提供商，其緊湊型CPU具有高的可靠性和穩(wěn)定性。它們經(jīng)過(guò)嚴(yán)格的測(cè)試和驗(yàn)證，可以在惡劣的工業(yè)環(huán)境下運(yùn)行。NETMERCURY 130-036 KEYBOARD
