8643型基础现场总线Profibus配电箱 burkert

类型描述

通过 8643 型电源 I/O 配电箱，可以用低成本将分散的二进制信号连接到一个过程控制系统上。通过一个符合 IEC 61158 的现场总线进行通讯。硬件具有 4 个本安型数字输出端，利用这些输出端可以控制大多数的本安型激励器，比如电磁阀、继电器或信号灯。8 个符合 Namur 技术规格的本安型数字输入端，使得二进制传感器的供货范围非常广泛。因此，在选择激励装置和传感装置时，用户不会被限制在特定的制造商上。带有 FF-H1 端口的版本能够提供不同形式的 DO 和 DI 功能块，从而可以满足编程员的各种需求。不同的外壳材料，比如聚酯或铝，也能扩展产品的适用范围。

（1）将二进制信号经济地连接到一个中央自动化装置上

（2）可连接最多 4 个先导阀和 8 个 NAMUR 感应开关

（3）集成式诊断和监控功能
 

Type 8643 - Power I/O Box for Foundation Fieldbus and Profibus PA

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
