Advantech ADAM-4520-D2E 隔離RS-232到RS-422/485轉換器

堅固耐用工業級塑料設計模塊，適用于惡劣環境

這些數據采集模塊結構小巧，多功傳感器到計算機接口單元，可以獨立提供智能信號調理，模擬和數字I / O，數據顯示和RS-485通訊。微處理器控制的Σ-△A / D轉換器接收信號，如電壓，電流，熱電偶或熱電阻傳感器。模塊支持Modbus的? / RTU協議的遠程數據傳輸機制，并使用行業標準的RS-485通信協議，允許您長距離高效傳輸和接收數據。固態繼電器切換輸出通道控制加熱器，泵和其他電力設備，各單位提供3000 V 直流隔離保護您的設備。所包含的Windows ?工具軟件可配置節點地址，波特率、通信協議、輸入范圍,校準設置等等。

包括：Windows ? Utility軟件中繼器/轉換器

中繼器型號18808-26放大，并提升現有的RS- 422/485信號延長通信距離到4000英尺，并能增加連接節點的最大數量32。型號18808-28 RS-232信號轉換成隔離的RS-422或485信號（不需要改變你的電腦的硬件或軟件）。型號18808-30是一個端口USB到RS-232/422/485轉換器，使用一個USB接口，可讓您連接串行設備的系統，。

數據網關

型號18808-32之間提供一個網關RS-232/422 / 485以太網接口，是專為通過互聯網遠程控制和監測設備。使用型號18808-36現有設備或控制器上運行Modbus串行協議（MODBUS / ASCII或Modbus / RTU）到以太網網絡連接。

Modules are designed with rugged industrial grade plastic for harsh environments

These data acquisition modules are compact, versatile sensor-to-computer interface units that independently provide intelligent signal conditioning, analog and digital I/O, data display and RS-485 communication. Microprocessor controlled sigma-delta A/D converters receive sensor signals such as voltage, current, thermocouples or RTD’s. Modules support the Modbus?/RTU protocol as the remote data transmission mechanism and use industry standard RS-485 communication protocol that allows you to transmit and receive data at high rates over long distances. Switching solid state relays allow the output channels to control heaters, pumps, and other power equipment, and units protect your equipment by providing 3000 V DC isolation. The included Windows? Utility software allows you to configure the node address, baud rate, communication protocol, input ranges, calibration settings and more.

What's included: Windows? Utility software.

Repeaters/Converters

Repeater model 18808-26 amplifies and boosts existing RS-422/485 signals extending the communication distance by 4000 ft and can increase the maximum number of connected nodes by 32. Model 18808-28 converts RS-232 signals into isolated RS-422 or 485 signals (no need to change your PC’s hardware or software). Model 18808-30 is a one port USB to RS-232/422/485 converter that allows you to connect a serial device to a system that uses a USB interface.
