：無機械觸點,因此沒有觸點的磨損,使用壽命接近于無限,它的長壽命、高信賴性是機械式繼電器無法相比的；光耦合繼電器的驅動部分具有光耦特性,抑制干擾傳輸；無動作聲音、無彈跳、防震；AC/DC兼用；低電流控制、高隔離電壓、高速切換、低泄漏電流；可控制各種負載(微小模擬信號的切換、繼電器、電燈、發光二極管、加熱器、馬達、電磁吸筒等)。
OMRON繼電器應用領域：廣泛應用于測量儀器、通訊器械(數據機、電子交換系統、PBX、多功能機、傳真機)、工業器械、醫療器械、安全系統、家電、辦公自動化、監測系統、可編程控制器、等領域。

歐姆龍繼電器優缺點:

1優點(dian)（1）高(gao)(gao)(gao)(gao)壽(shou)(shou)命，高(gao)(gao)(gao)(gao)可靠(kao)：固(gu)態(tai)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)沒(mei)有(you)機械(xie)零部件(jian)(jian)，由固(gu)體(ti)器(qi)(qi)件(jian)(jian)完成(cheng)觸點(dian)功能(neng)，由于(yu)沒(mei)有(you)運動的(de)(de)零部件(jian)(jian)，因此(ci)能(neng)在高(gao)(gao)(gao)(gao)沖擊，振動的(de)(de)環境下工作，由于(yu)組成(cheng)固(gu)態(tai)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)元器(qi)(qi)件(jian)(jian)的(de)(de)固(gu)有(you)特性，決定了(le)(le)固(gu)態(tai)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)壽(shou)(shou)命長，可靠(kao)性高(gao)(gao)(gao)(gao)。固(gu)態(tai)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)（2）靈(ling)敏度高(gao)(gao)(gao)(gao)，控制功率小，電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)兼(jian)容性好：固(gu)態(tai)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)輸入電(dian)(dian)(dian)(dian)(dian)(dian)壓范圍較寬，驅動功率低，可與大(da)多數邏輯集成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)路兼(jian)容不需加緩(huan)沖器(qi)(qi)或驅動器(qi)(qi)。（3）快速轉換(huan)：固(gu)態(tai)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)因為采(cai)用(yong)固(gu)體(ti)器(qi)(qi)件(jian)(jian)，所以切換(huan)速度可從(cong)幾(ji)毫秒至幾(ji)微妙(miao)。（4）電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)干(gan)(gan)擾(rao)小：固(gu)態(tai)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)沒(mei)有(you)輸入“線(xian)圈”，沒(mei)有(you)觸點(dian)燃弧和回跳，因而減(jian)少了(le)(le)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)干(gan)(gan)擾(rao)。大(da)多數交(jiao)流(liu)輸出固(gu)態(tai)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)是一(yi)個(ge)零電(dian)(dian)(dian)(dian)(dian)(dian)壓開(kai)關，在零電(dian)(dian)(dian)(dian)(dian)(dian)壓處(chu)導(dao)通，零電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)處(chu)關斷(duan)，減(jian)少了(le)(le)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)波(bo)形的(de)(de)突然中斷(duan)，從(cong)而減(jian)少了(le)(le)開(kai)關瞬(shun)態(tai)效應(ying)。

2:缺點(dian)(dian)（1）導(dao)(dao)通后的(de)(de)(de)管(guan)壓(ya)(ya)降(jiang)(jiang)大，可(ke)控硅(gui)或(huo)雙向(xiang)(xiang)控硅(gui)的(de)(de)(de)正向(xiang)(xiang)降(jiang)(jiang)壓(ya)(ya)可(ke)達1~2V，大功(gong)率(lv)晶體管(guan)的(de)(de)(de)飽和壓(ya)(ya)降(jiang)(jiang)也(ye)(ye)在1~2V之間，一般功(gong)率(lv)場效應管(guan)的(de)(de)(de)導(dao)(dao)通電(dian)(dian)(dian)(dian)阻(zu)也(ye)(ye)較(jiao)機(ji)械觸(chu)點(dian)(dian)的(de)(de)(de)接(jie)觸(chu)電(dian)(dian)(dian)(dian)阻(zu)大。（2）半(ban)導(dao)(dao)體器(qi)件關斷后仍(reng)可(ke)有數(shu)微安至數(shu)毫安的(de)(de)(de)漏電(dian)(dian)(dian)(dian)流(liu)，因此不能(neng)實現理想(xiang)的(de)(de)(de)電(dian)(dian)(dian)(dian)隔離。（3）由于管(guan)壓(ya)(ya)降(jiang)(jiang)大，導(dao)(dao)通后的(de)(de)(de)功(gong)耗和發熱(re)(re)量也(ye)(ye)大，大功(gong)率(lv)固(gu)態繼電(dian)(dian)(dian)(dian)器(qi)的(de)(de)(de)體積遠遠大于同(tong)容量的(de)(de)(de)電(dian)(dian)(dian)(dian)磁(ci)繼電(dian)(dian)(dian)(dian)器(qi)，成本也(ye)(ye)較(jiao)高。（4）電(dian)(dian)(dian)(dian)子元器(qi)件的(de)(de)(de)溫度(du)(du)特(te)性和電(dian)(dian)(dian)(dian)子線路的(de)(de)(de)抗干擾能(neng)力(li)較(jiao)差，耐輻(fu)射能(neng)力(li)固(gu)態繼電(dian)(dian)(dian)(dian)器(qi)也(ye)(ye)較(jiao)差，如不采取有效措施(shi)，則工作可(ke)靠性低。（5）固(gu)態繼電(dian)(dian)(dian)(dian)器(qi)對過載(zai)(zai)(zai)有較(jiao)大的(de)(de)(de)敏感性，必(bi)須用快(kuai)速熔斷器(qi)或(huo)RC阻(zu)尼電(dian)(dian)(dian)(dian)路對其進行過載(zai)(zai)(zai)保護。固(gu)態繼電(dian)(dian)(dian)(dian)器(qi)的(de)(de)(de)負載(zai)(zai)(zai)與環(huan)境(jing)溫度(du)(du)明顯有關，溫度(du)(du)升(sheng)高，負載(zai)(zai)(zai)能(neng)力(li)將迅(xun)速下降(jiang)(jiang)。（6）主(zhu)要(yao)不足是存在通態壓(ya)(ya)降(jiang)(jiang)（需相應散熱(re)(re)措施(shi)），有斷態漏電(dian)(dian)(dian)(dian)流(liu)，交(jiao)直流(liu)不能(neng)通用，觸(chu)點(dian)(dian)組數(shu)少，另外過電(dian)(dian)(dian)(dian)流(liu)、過電(dian)(dian)(dian)(dian)壓(ya)(ya)及電(dian)(dian)(dian)(dian)壓(ya)(ya)上升(sheng)率(lv)、電(dian)(dian)(dian)(dian)流(liu)上升(sheng)率(lv)等指標差。
