中間繼電器在選型時觸點是一個重要的參數(shù)，可以簡單的理解為開關常開或者常關使信號接通或者斷開的接點就叫繼電器的觸點。聚仁繼電器的觸點數(shù)量一般以3位數(shù)表示，例如：220（表示2副常開觸點2副常閉觸點），402（表示4副常開觸點2副轉(zhuǎn)換觸點），026（表示2副常閉觸點6副轉(zhuǎn)換觸點），008（表示8副轉(zhuǎn)換觸點），422（表示4副常開觸點2副常閉觸點2副轉(zhuǎn)換觸點），也有的用H表示常開觸點，例如2H（表示2副常開觸點），4D（表示4副常閉觸點），ZJS-305監(jiān)視中間繼電器，6Z（表示6副轉(zhuǎn)換觸點）。以往的一些繼電器選型采用代號表示，例如1表示2常開2常閉等，導致選型錯誤，而聚仁的選型更容易理解，ZJS-305監(jiān)視中間繼電器，從左往右的數(shù)字順序分別對應常開，ZJS-305監(jiān)視中間繼電器、常閉、轉(zhuǎn)換這三種觸點類型，方便選型和備貨。導軌安裝中間繼電器，只需要在開關柜內(nèi)安裝導軌條，無需開孔，并支持多個拼接。ZJS-305監(jiān)視中間繼電器</p><div

style="text-indent:25px">中間繼電器的用途范圍廣，主要是用其常開或常閉觸點來控制一個或多個較大負荷電流(10A以上)的線路開關（主要是接觸器和斷路器）,作為控制按鈕或微型開關與較大負荷電流的電路開關元件之冋的一個控制信號傳遞環(huán)節(jié)。也可以用于直接控制較小電流(10A或5A以下)的線路或用電設備,例如照明燈、指示燈、電鈴、小容量電爐、小容量電動機、小型風扇等，此時相當于個小容量的接觸器。可以說中間繼電器的用途涵蓋了電力、工業(yè)控制、家用電器、樓宇照明等多個領域。DZK-914快速中間繼電器價格中間繼電器采用小型繼電器線圈應用于電梯上，能保障電梯的可靠運行。</p><div

style="text-indent:25px">中間型的繼電器用于各種保護和自動控制線路中作為輔助繼電器，以增加接點的數(shù)量及接點容量。主要實現(xiàn)以下作用：1、隔離：控制系統(tǒng)的輸出信號與負載端電氣隔離。2、轉(zhuǎn)換：比如控制系統(tǒng)輸出信號為DC24V，但負載使用AC220V供電，對于輸入可逆。3、放大：控制器輸出的信號的帶負載的能力往往有限，在mA或者數(shù)A的級別，如果有需要更大電流的負載，只能通過中間型繼電器來轉(zhuǎn)換。4、便于維護：即使是滿足負載電流要求的輸出端，但因為集成在控制器內(nèi)部，如果損壞，更換維修比較麻煩，但如果通過中間繼電器，輸出端的負載只是繼電器的線圈，減輕了控制器輸出級的負載，從而降低損壞的幾率。而當中間繼電器觸點因為頻繁的使用損壞時，采用插拔式接線端子的中間繼電器就能很容易通過簡單的插拔完成更換。</p><p

style="text-indent:25px">中間繼電器按電路類型可分為靜態(tài)集成電路和電磁式這兩種，電磁式繼電器主要由電磁機構(gòu)和觸點組成，其特點是在線圈兩端加上電壓或通入電流，產(chǎn)生電磁力，當電磁力大于彈簧反力時，吸動銜鐵使常開常閉接點動作，當線圈的電壓或電流下降或消失時銜鐵釋放，接點復位。其結(jié)構(gòu)簡單、價格低、觸點容量小、觸點數(shù)量少、無主輔之分、體積大等缺點。而聚仁電力采用靜態(tài)集成電路型中間繼電器主要采用PLC電路進行控制，主要由控制芯片、線圈、電容等組成。具有觸點容量大、觸點數(shù)量多、體積小、動作精度高、動作準確、安裝方便。隨著技術的不斷改進，電磁式繼電器逐漸被靜態(tài)電路型所替換。中間繼電器線圈不通電處于閉合狀態(tài)的兩組觸點稱之為動斷型觸點又稱為常閉觸點，用數(shù)字加字母D表示。SRS-110VDC-3Z-10A生產(chǎn)廠家</p><p style="text-indent:25px">中間繼電器應用于工業(yè)自動化控制設備中，通過時間延時來判斷觸點的動作和閉合，使設備能夠精確的運行。ZJS-305監(jiān)視中間繼電器</p><p style="text-indent:25px">傳統(tǒng)的老式中間繼電器的整體結(jié)構(gòu)是由中間機構(gòu)、承受機構(gòu)以及執(zhí)行機構(gòu)等這三個重要部分組成。其中承受機構(gòu)的作用就是為了能夠精確的反映出繼電器自身的輸入量，同時并傳遞到中間機構(gòu)中和提前設定的量（也就是整定值）讓兩個數(shù)值相互做出對比，在這個過程中要是檢測出達到了整定值時（過量或者欠量）則中間機構(gòu)就會促使執(zhí)行機構(gòu)進行動作，將其的觸點閉合以及斷開從而實現(xiàn)了某一種設備控制的目的。而電磁式中間繼電器其中間機構(gòu)采用電磁式設計，有時候反映的輸入量不準確，而執(zhí)行機構(gòu)采用線圈操作，由于線圈的匝數(shù)是采用從工制作，有時數(shù)量會不一樣，從而導致閉合或斷開的時間不準確。而聚仁電力采用靜態(tài)電路的中間繼電器，其中間機構(gòu)采用芯片控制，而執(zhí)行機構(gòu)采用電路模擬判斷，在處理上和判斷上比電磁式更準確。ZJS-305監(jiān)視中間繼電器</p><p
