型號(hào)描述
通過(guò) 8643 型電源 I/O 配電箱，可以用低成本將分散的二進(jìn)制信號(hào)連接到一個(gè)過(guò)程控制系統(tǒng)上。通過(guò)一個(gè)符合 IEC 61158 的現(xiàn)場(chǎng)總線進(jìn)行通訊。硬件具有 4 個(gè)本安型數(shù)字輸出端，利用這些輸出端可以控制大多數(shù)的本安型激勵(lì)器，比如電磁閥、繼電器或信號(hào)燈。8 個(gè)符合 Namur 技術(shù)規(guī)格的本安型數(shù)字輸入端，使得二進(jìn)制傳感器的供貨范圍非常廣泛。因此，在選擇激勵(lì)裝置和傳感裝置時(shí)，用戶不會(huì)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(kuò)展產(chǎn)品的適用范圍。
1）將二進(jìn)制信號(hào)經(jīng)濟(jì)地連接到一個(gè)自動(dòng)化裝置上
2）可連接最多 4 個(gè)先導(dǎo)閥和 8 個(gè) NAMUR 感應(yīng)開(kāi)關(guān)
3）集成式診斷和監(jiān)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
