光電轉(zhuǎn)換器 TBC系列工業(yè)串口光纖貓將RS232/422/485電信號直接調(diào)制成光信號在光纖上傳輸，具有體積小巧，使用方便靈活的特點(diǎn)。該產(chǎn)品突破了傳統(tǒng)的接口通訊距離與通訊速率的矛盾，同時(shí)，也解決了電磁干擾、地環(huán)干擾和雷電破壞的難題，大大提高了數(shù)據(jù)通訊的可靠性、安全性和保密性，可廣泛用于各種工業(yè)控制、過程控制和交通控制等場合，特別適合銀行、電力及對電磁干擾環(huán)境有特殊要求的部門和系統(tǒng)。通用級高性能光隔RS-232/RS-422/RS-485轉(zhuǎn)換器，通過開關(guān)設(shè)置，既可支持RS-232/RS-485雙向轉(zhuǎn)換亦可支持RS-232/RS-422雙向轉(zhuǎn)換。其壁掛式外型設(shè)計(jì)支持DIN-rail標(biāo)準(zhǔn)導(dǎo)軌安裝，安裝簡便,此外采用單端供電技術(shù)實(shí)現(xiàn)光隔，其RS-232端采用獨(dú)立外供電，而RS-485/422端采用DC/DC隔離變換提供電源，通信信號采用高速光耦隔離。這種設(shè)計(jì)能夠有效避免工程中由于共用電源帶來的隔離失效,稱為真正\"隔離\"。應(yīng)用特征采用先進(jìn)的通信編碼及時(shí)鐘恢復(fù)技術(shù)實(shí)現(xiàn)許多企業(yè)采用低成本的直接光調(diào)制方式實(shí)現(xiàn)串口到光纖的轉(zhuǎn)換，然而由于光色散及信號抖動的存在，信號從電到光而后又從光到電的變化過程中必然存在信號展寬和變窄的可能，因此隨著傳輸距離和速度的變化該方法勢必存在數(shù)據(jù)出錯的可能。而采用先進(jìn)的通信編碼及時(shí)鐘恢復(fù)技術(shù)能夠有效的避免該現(xiàn)象的出現(xiàn)，而且傳輸距離更遠(yuǎn)。零延時(shí)自動轉(zhuǎn)發(fā)采用獨(dú)特的“零延時(shí)自動轉(zhuǎn)發(fā)”技術(shù)，增強(qiáng)了接口的抗干擾能力，使接收和發(fā)送能夠自動轉(zhuǎn)發(fā)，達(dá)到真正的零延時(shí)！自動數(shù)據(jù)流控（ADDC）采用嵌入式自動數(shù)據(jù)流控（ADDC）技術(shù)，實(shí)行硬件數(shù)據(jù)流解決方案，不使用握手信號就能自動檢測控制數(shù)據(jù)方向，從而解決了RS-485數(shù)據(jù)流向控制限制問題。自動偵測串口速率能夠進(jìn)行波特率自動偵測，即使設(shè)備的串行信號波特率改變了，轉(zhuǎn)換器仍然可以實(shí)現(xiàn)RS-232或RS-485/422到光的轉(zhuǎn)換傳輸。產(chǎn)品說明自動偵測串口速率、判別和控制數(shù)據(jù)傳輸方向數(shù)據(jù)傳輸速率0-115.2Kbps自適應(yīng)；采用先進(jìn)的通信編碼及時(shí)鐘恢復(fù)技術(shù)實(shí)現(xiàn)，確保信號完整性一體化光收發(fā)模塊，輸出光功率穩(wěn)定可靠；全透明通信，用戶無須任何調(diào)試，即插即用；特有接口自適應(yīng)技術(shù)，無需開關(guān)設(shè)置，隨意切換RS-485/RS-422接口具有自動偵測信號速率功能RS-485信號零延時(shí)自動轉(zhuǎn)發(fā)單端9V供電，另端采用5VDC-DC電源隔離3000V，無需串口取電信號傳輸采用3000V高速光隔及預(yù)加重技術(shù)通信距離長達(dá)3000米（9600BPS）支持32點(diǎn)輪詢環(huán)境（可定制128點(diǎn)）接口具有1500W浪涌保護(hù)，15KV靜電保護(hù)485/422接口形式采用RJ45,COM口及5位接線端子可任選支持DIN-Rail導(dǎo)軌安裝和面板式安裝方式技術(shù)參數(shù)標(biāo)準(zhǔn)：符合EIARS-232,RS-485,RS-422標(biāo)準(zhǔn)RS-232信號：TX，RX，GNDRS-485信號：D ，D-，GNDRS-422信號：R ，R-，T ，T-，GND接收靈敏度：優(yōu)于-36dBm（BER e-11）光路編碼：加擾NRZ碼發(fā)送功率：-9dBm/-5dBm工作方式：異步工作，點(diǎn)對點(diǎn)或多點(diǎn)，2線半雙工，4線全雙工方向控制：采用數(shù)據(jù)流向自動控制技術(shù)，自動判別和控制數(shù)據(jù)傳輸方向波特率：300-115200bps，自動偵測串口信號速率負(fù)載能力：支持32點(diǎn)輪詢環(huán)境(可定制128點(diǎn))傳輸距離：RS-485/422端3000米(9600bps時(shí))，RS-232端建議不超過5米接口保護(hù)：1500W浪涌保護(hù)、15KV靜電保護(hù)光電隔離：3000V接口特性：滿足ITU-TV.24標(biāo)準(zhǔn)接口形式：RS-232端DB-9母頭，RS-485/422DB-9公頭，RJ45座或5位接線端子工作溫度：-20℃~60℃存儲溫度：-25℃~85℃相對濕度：5%~95%輸入電源：9V供電功耗：靜態(tài)功耗120mA以內(nèi)，動態(tài)功耗平均值300mA以內(nèi)指示燈：POWER：電源指示TX：光纖接口發(fā)送數(shù)據(jù)指示Rx：光纖接口接收數(shù)據(jù)指示訂購信息型號：TBC-3218(光纖轉(zhuǎn)RS232)TBC-3268（光纖轉(zhuǎn)RS422/485)TBC-3168(光纖轉(zhuǎn)RS232/422/482)選項(xiàng)：傳輸距離D40：單模雙纖40kmS40：單模單纖40km光接口類型F：FCS：SCProducts Content:Everything is networked is rapidly becoming the norm for enterprises the world over, and to keep pace with the trend of networked-based automation, devices must be networked in order to form an automatic data collection system for quality control, production monitoring, or even real-time cost management.
