摘要： A housing for a control apparatus is made of a synthetic material and includes a lower part and a cover. In the lower part are provided an upper printed board and one or more lower printed boards. Additional modules can be connected with the upper printed board by means of connectors. The lower printed boards are inserted on supporting ribs and between guiding ribs under the upper printed board and in the inserted condition they are exchangeably connected with a printed bus. At the bottom of the lower part of the housing is fastened a screening sheet. The housing of the apparatus can be realized at low costs and due to the screening sheet, a sufficient screening can be guaranteed. The two or three stages permit a compact construction of the apparatus and notwithstanding, all printed boards are easily accessible, in that the lower printed boards are to be removed without any dismounting of the upper printed board. The construction of the apparatus and of the printed boards permit different kinds of insertions of the apparatus as well as a simple exchange of the printed boards and thus versatile possibilities of designs.

摘要： An operator interface panel assembly is used with a programmable logic controller. Through the use of a printed wired circuit board, a wide variety of input and output components that must be accessible to an operator can be assembled by the user at the location of the installation rather than at the point of manufacture. The assembly can be easily reconfigured without costly rewiring of the installation. The same switch or pilot light position can accommodate a variety of one and two pole switches without hardware modification.
摘要翻译：操作员界面面板组件与可编程逻辑控制器一起使用。通过使用印刷的有线电路板，用户可以在安装位置而不是在制造过程中组装必须能够操作的各种输入和输出部件。组装可以轻松重新配置，而无需昂贵的重新布线设备。相同的开关或指示灯位置可以容纳各种一个和两个极开关，而不需要硬件修改。

摘要： An electrical time-switch has two relays on a circuit board with electrical connector blades extending from it. A backplate carrying cable connectors is provided with slots such that it can be fitted over the blades, making electrical connection between the cable connectors and the circuit board, with either face exposed. Thus the same backplate can be used for both wall-mounting and panel-mounting, while maintaining ease of access to the cable connectors for cable attachment. An optional unit with a second pair of relays can be fitted on the circuit board and has additional blades for connection to the extra relays.
摘要翻译：电气时间开关在电路板上具有两个继电器，电连接器叶片从其延伸。背板承载电缆连接器设置有槽，使得其可以安装在叶片上方，使得电缆连接器和电路板之间的电连接（两个面都暴露）。因此，相同的背板可以用于墙壁安装和面板安装，同时保持对电缆连接器的电缆连接器的容易的访问。具有第二对继电器的可选单元可以安装在电路板上，并具有用于连接到额外继电器的附加刀片。
