型號描述
通過 8643 型電源 I/O 配電箱，可以用低成本將分散的二進制信號連接到一個過程控制系統上。通過一個符合 IEC 61158 的現場總線進行通訊。硬件具有 4 個本安型數字輸出端，利用這些輸出端可以控制大多數的本安型激勵器，比如電磁閥、繼電器或信號燈。8 個符合 Namur 技術規格的本安型數字輸入端，使得二進制傳感器的供貨范圍非常廣泛。因此，在選擇激勵裝置和傳感裝置時，用戶不會被限制在特定的制造商上。帶有 FF-H1 端口的版本能夠提供不同形式的 DO 和 DI 功能塊，從而可以滿足編程員的各種需求。不同的外殼材料，比如聚酯或鋁，也能擴展產品的適用范圍。
1）將二進制信號經濟地連接到一個自動化裝置上
2）可連接最多 4 個先導閥和 8 個 NAMUR 感應開關
3）集成式診斷和監控功能
Type Description
With the Power I/O Box Type 8643, Bürkert offers a system that allows extremely cost effective connection of distributed binary signals to a process control system. Communication takes place via field bus in accordance with the EC 61158-2 standard. The hardware offers 4 intrinsically safe digital outputs making it possible to control a wide range of intrinsically safe actuators such as solenoid valves, relays or indicator lights. 8 intrinsically safe digital inputs operate in accordance with Namur specifications. This enables a broad spectrum of binary sensors ensuring that users are not limited to a specific manufacturer when selecting actuator or sensor technology. The device with the FF H1 interface offers DO and DI function blocks in a number of different versions in order to meet all of the demands programmers place on such systems. A variety of housing materials including polyester and aluminium offers additional enhancements for the field of application.
1）Efficient connection of binary signals to a central automation system
2）Connection of up to 4 pilot valves and 8 NAMUR proximity switches
3）Integrated diagnostic and monitoring functions
