產(chǎn)品概述
FT-BC-2112 RS-232串行口光電隔離器又稱為串口隔離器(ISOLATORS),它采用了的光電隔離技術(shù),極大限度地保護(hù)了RS-232串行接口設(shè)備,避免了地線回路電壓、浪涌、感應(yīng)雷擊、靜電、熱插拔等惡劣環(huán)境對(duì)RS-232設(shè)備的損壞。
RS-232接口的損壞是通信設(shè)備硬件的損壞,造成的原因90%以上是由于兩端設(shè)備不共地、各類浪涌、感應(yīng)雷擊、靜電干擾、熱插拔,電磁干擾等惡劣環(huán)境對(duì)RS-232設(shè)備的損壞。比如設(shè)備A和設(shè)備B使用RS-232接口相連,如果A和B之間的地線之間有大于50V的電壓差(經(jīng)常會(huì)達(dá)到80V以上),則RS-232通信就會(huì)不正常,RS-232接口可以隨瞬間2500Vrms,連續(xù)500VDC的峰值電壓差,還可以有效吸收靜電和電磁干擾,保護(hù)設(shè)備的RS-232接口。
由于采用了光電隔離技術(shù),隔離了兩端RS-232設(shè)備的電氣與地線回路,使得一側(cè)的電信號(hào)變成光信號(hào)以后傳到另一方,在變回到電信號(hào),從而保護(hù)通信設(shè)備免受電源地線回路和浪涌的干擾和損壞,明顯地提高了通信系統(tǒng)的可靠與穩(wěn)定性。
FT-BC-2112產(chǎn)品已經(jīng)被廣泛應(yīng)用于電力、保險(xiǎn)、電信、鐵路、郵局、金融、銀行、證券、程控等行業(yè)的點(diǎn)到點(diǎn)RS-232通信系統(tǒng)、UNIX多用戶系統(tǒng)、監(jiān)視控制系統(tǒng)、程控交換機(jī)計(jì)費(fèi)終端、衛(wèi)星接收機(jī)、ATM自動(dòng)等領(lǐng)域。
