    Abstract: A fieldbus coupler for coupling a local fieldbus network utilizing a first fieldbus protocol to a foreign field device or foreign fieldbus network through an interconnecting wired or wireless network transmission line that utilizes a second fieldbus protocol different from the first fieldbus protocol includes a first circuit configured to communicate over the local fieldbus network using the first fieldbus protocol, a second circuit configured to connect the fieldbus coupler with the interconnecting network transmission line and communicate over the interconnecting network transmission line using the second fieldbus protocol, and a third circuit configured to communicate with the first and second circuits and capable of transmitting data to and from the first and second circuits to enable communications between the local fieldbus network via the interconnecting network transmission line.

    Abstract: A base element and a surge protection system incorporating the base element are provided. The base element includes a housing having a front portion and a rear portion. Apertures in the rear portion provide access to contacts secured within the housing, and a receiving portion extending from the front portion includes at least one receiving section for receiving a surge protection cartridge. Plug receptacles in the receiving portion are in electrical communication with the contacts to incorporate the surge protection device in a circuit when the surge protection cartridge is inserted. The base element is configured to mount orthogonally to a case such that conductors secured to the contacts extend through the apertures and into an enclosure defined by the case in a substantially linear direction. The system includes a case configured to be attached to a rack mount system and a plurality of base elements secured to the case.

    Abstract translation: 提供了一种结合基座元件的基座元件和浪涌保护系统。 基座元件包括具有前部和后部的壳体。 后部的孔径提供对固定在壳体内的触点的接触,并且从前部延伸的接收部分包括用于接收浪涌保护盒的至少一个接收部分。 接收部分中的插座与触点电连通,当浪涌保护盒插入时,将电涌保护装置并入电路中。 基座元件被配置为垂直于壳体安装,使得固定到触头的导体延伸穿过孔并进入由壳体沿大致线性方向限定的壳体。 该系统包括被配置为附接到机架安装系统的壳体和固定到壳体的多个基座元件。
