關於 繼電器
繼電器以電氣控制訊號切換隔離觸點,應用於訊號、電力及控制電路。機電式產品以線圈吸動銜鐵,磁保持型則可在驅動脈衝結束後維持狀態。產品包括電路板、插座及面板安裝的訊號或功率繼電器、簧片繼電器、安全繼電器和相關輸出模組,常見於家電、工業控制、樓宇系統、通訊、車輛及測試設備。
選型應確認線圈類型與額定電壓、觸點形式、極數及安裝方式。觸點額定值必須匹配實際切換電壓、電流與負載類型;阻性、感性、馬達、燈具及電容性負載的浪湧和分斷要求差異很大。另需核對最小切換負載、吸合與釋放電壓、線圈功耗、絕緣、接觸電阻、切換時間及機械/電氣壽命,以及溫度降額、密封或可清洗性、插座相容性和認證。腳位相似不代表負載壽命或安全性能相同。
