FB485-E
RS-232轉(zhuǎn)RS-485/422通用型雙向轉(zhuǎn)換器
FB485-E串口轉(zhuǎn)換器通過從RS-232端口取電來實現(xiàn)RS-232到RS-422/485轉(zhuǎn)換，它將RS-232的TxD和 RxD信號轉(zhuǎn)換為半雙工的2線RS-485差分信號或全雙工的4線RS-422/485信號。FB485-E RS232轉(zhuǎn)RS485/422 轉(zhuǎn)換器內(nèi)建有15KV ESD浪涌保護功能，可防止輸出信號的電流突波。FB485-E還提供了通過檢測RS-232輸出信號TxD狀態(tài)來實現(xiàn)RS-485自動數(shù)據(jù)流向控制的功能。因此，客戶不必自行控制RS-485數(shù)據(jù)的流向。
特點：
串口取電或外部供電；
串口可帶電熱插撥；
2/4線RS-485和RS-422方式可選
內(nèi)置RS-485自動數(shù)據(jù)流向控制；
支持128節(jié)點輪詢網(wǎng)絡結(jié)構(gòu)；
波特率50bps-115.2kbps；
通信距離0~3Km；
內(nèi)置15KV ESD保護
FB485-CHG/CPG
RS-232轉(zhuǎn)RS-485/422有源光電隔離轉(zhuǎn)換器（工業(yè)RAIL機殼）
FB485-CPG/CHG串口轉(zhuǎn)換器實現(xiàn)RS-232到RS-485/422隔離轉(zhuǎn)換，它將RS-232的TxD和 RxD信號轉(zhuǎn)換為半雙工的2線RS-485差分信號或全雙工的4線RS-422差分信號。FB485-CHG 的RS-232側(cè)由串口取電，F(xiàn)B485-CPG的RS-232側(cè)由內(nèi)嵌的DC-DC供電，RS-485側(cè)由外部+5V或+9~+30VDC(Vs)電源供電，RS-232側(cè)和RS-485側(cè)通過光電隔離實現(xiàn)3000V的隔離保護。FB485-CPG內(nèi)建有15KV ESD浪涌保護功能，可防止輸出信號的電流突波。FB485-CPG RS232轉(zhuǎn)RS485/422隔離轉(zhuǎn)換器還提供了通過檢測RS-232輸出信號TxD狀態(tài)來實現(xiàn)RS-485自動數(shù)據(jù)流向控制的功能。因此，客戶不必自動控制RS-485數(shù)據(jù)的流向。正面有電源和數(shù)據(jù)收發(fā)指示燈，便于客戶直觀地了解FB485-CPG轉(zhuǎn)換器的工作狀態(tài)。
特點：
FB485-CHG：RS-232側(cè)由串口取電; FB485-CPG：RS-232側(cè)由內(nèi)嵌的DC-DC供電
RS-485/422側(cè)+5V或+9~+30VDC(Vs)電源供電
3000V隔離保護
結(jié)構(gòu)緊湊, 配一體化工業(yè)接線端子,標準孔式DB9,適合工業(yè)RAIL導軌安裝
2線RS-485半雙工通信，4線RS-422全雙工通信
RS-485自動數(shù)據(jù)流向控制
自動偵測波特率
15KV ESD浪涌保護
