FB485-E
RS-232轉RS-485/422通用型雙向轉換器
FB485-E串口轉換器通過從RS-232端口取電來實現RS-232到RS-422/485轉換，它將RS-232的TxD和 RxD信號轉換為半雙工的2線RS-485差分信號或全雙工的4線RS-422/485信號。FB485-E RS232轉RS485/422 轉換器內建有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狀態來實現RS-485自動數據流向控制的功能。因此，客戶不必自行控制RS-485數據的流向。
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
內置RS-485自動數據流向控制；
支持128節點輪詢網絡結構；
波特率50bps-115.2kbps；
通信距離0~3Km；
內置15KV ESD保護
FB485-CHG/CPG
RS-232轉RS-485/422有源光電隔離轉換器（工業RAIL機殼）
FB485-CPG/CHG串口轉換器實現RS-232到RS-485/422隔離轉換，它將RS-232的TxD和 RxD信號轉換為半雙工的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側由串口取電，FB485-CPG的RS-232側由內嵌的DC-DC供電，RS-485側由外部+5V或+9~+30VDC(Vs)電源供電，RS-232側和RS-485側通過光電隔離實現3000V的隔離保護。FB485-CPG內建有15KV ESD浪涌保護功能，可防止輸出信號的電流突波。FB485-CPG RS232轉RS485/422隔離轉換器還提供了通過檢測RS-232輸出信號TxD狀態來實現RS-485自動數據流向控制的功能。因此，客戶不必自動控制RS-485數據的流向。正面有電源和數據收發指示燈，便于客戶直觀地了解FB485-CPG轉換器的工作狀態。
特點：
FB485-CHG：RS-232側由串口取電; FB485-CPG：RS-232側由內嵌的DC-DC供電
RS-485/422側+5V或+9~+30VDC(Vs)電源供電
3000V隔離保護
結構緊湊, 配一體化工業接線端子,標準孔式DB9,適合工業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自動數據流向控制
自動偵測波特率
15KV ESD浪涌保護
