公告800T水密/油密选择开关产品数据除了标准的2、3和4位电路外，公告800T选择开关在满足特殊电路要求方面具有很大的灵活性。本出版物将帮助您选择特殊的Bulletin 800T选择器开关操作器和/或提供特定触点操作顺序的触点块，并且还将帮助您在需要无触点配置时在现场选择触点块。本出版物适用于公告800T T系列和800H F系列选择器开关。Bulletin 800T选择器开关在旋转凸轮开关后面构造有两个致动器，它们独立操作以提供各种接触顺序。根据所需的致动顺序，接触块可以一个接一个地堆叠或并排堆叠。堆叠在第1侧（白色致动器）和第2侧（黑色致动器）上的接触块彼此独立地按下或松开。参见下图1。当从后部观察操作员组件时，操作员壳体上的三角形突起提供了1侧的正面指示，即白色致动器位置（也在设备铭牌上注明）。该惯例对于正确选择和安装接触块非常重要，如组合接触操作所示。操作员三角投影后视图显示侧1（白色致动器）白色致动器（侧1）黑色致动器（侧2）图1本出版物补充了Allen-Bradley工业控制目录中列出的选择器开关的广泛选择。目录中列出的选择器开关基于最流行的两位和三位凸轮布置，提供了一个简短而完整的目录编号。工业控制目录还列出了一些特殊的三位和四位选择器开关触点布置。该目录列出了（9）三位和（5）四位凸轮功能的选择，包括各种操作器和接触块布置。通过将运算符前缀与接触块后缀连接，可以简单地为这些单元组合目录号。安装选择开关基本标准与特殊形式公告800T油密选择开关产品数据2本出版物将帮助您选择更广泛的专用选择开关。通过选择单独的操作员、凸轮和接触块，可以指定选择器开关以满足您的需求。这三个组件可以组合成一个简单的目录号。新的易于使用的“模块化”目录编号系统用于简化订购。传统的目录编号系统最初是为了提供紧凑的目录编号而开发的，用于所有标准目录列出的两位和三位选择器开关。参考以下示例：800T–H 2 A接触块后缀操作员类型
A–B Bulletin 800T Watertight/Oiltight Selector Switches Product Data In addition to standard 2, 3, and 4 position circuits, Bulletin 800T selector switches provide a great deal of flexibility in meeting special circuit requirements. This publication will help you select special Bulletin 800T selector switch operators and/or contact blocks that provide a specific contact operating sequence and will also help you select contact blocks in the field when uncataloged configurations are required. This publication applies to Bulletin 800T Series T and 800H Series F selector switches. Bulletin 800T selector switches are constructed with two actuators behind a rotary cam switch that operate independently to provide various contact sequences. Contact blocks can be stacked one behind the other or side-by-side depending on the actuating sequence desired. The contact blocks stacked on Side 1 (white actuator) and Side 2 (black actuator) are depressed or released independently of each other. See Figure 1 below. When the operator assembly is viewed from the rear, the triangular projections on the operator housing provide positive indication of Side 1 which is the white actuator location (also noted on device nameplate). This convention is important for proper contact block selection and mounting, as illustrated in the combined contact operation. Rear View of Operator Triangular Projections Indicate Side 1 (White Actuator) White Actuator (Side 1) Black Actuator (Side 2) Figure 1 This publication supplements the broad selection of the selector switches listed in the Allen-Bradley Industrial Control catalog. Selector switches listed in the catalog are based on the most popular two and three position cam arrangements offering a short yet complete catalog number. The Industrial Control catalog also lists some special three and four position selector switch contact arrangements. The catalog lists a choice of (9) three-position and (5) four-position cam functions with various operators and contact block arrangements. Catalog numbers are simply assembled for these units by joining the operator prefix with the contact block suffix. Installation Selector Switch Basics Standard vs Special Forms Bulletin 800T Oiltight Selector Switches Product Data 2 This publication will help you select a greater range of specialized selector switches. A selector switch can be specified to meet your needs by selecting separate operators, cams and contact blocks. The three components can be combined into one simple catalog number. A new easy-to-use “modular” catalog numbering system is used to simplify ordering. The traditional catalog numbering system was originally developed to provide compact catalog numbers and is used on all standard catalog listed two-position and three-position selector switches.
