公告800T水密/油密選擇開關產品數據除了標準的2、3和4位電路外，公告800T選擇開關在滿足特殊電路要求方面具有很大的靈活性。本出版物將幫助您選擇特殊的Bulletin 800T選擇器開關操作器和/或提供特定觸點操作順序的觸點塊，并且還將幫助您在需要無觸點配置時在現場選擇觸點塊。本出版物適用于公告800T T系列和800H F系列選擇器開關。Bulletin 800T選擇器開關在旋轉凸輪開關后面構造有兩個致動器，它們獨立操作以提供各種接觸順序。根據所需的致動順序，接觸塊可以一個接一個地堆疊或并排堆疊。堆疊在第1側（白色致動器）和第2側（黑色致動器）上的接觸塊彼此獨立地按下或松開。參見下圖1。當從后部觀察操作員組件時，操作員殼體上的三角形突起提供了1側的正面指示，即白色致動器位置（也在設備銘牌上注明）。該慣例對于正確選擇和安裝接觸塊非常重要，如組合接觸操作所示。操作員三角投影后視圖顯示側1（白色致動器）白色致動器（側1）黑色致動器（側2）圖1本出版物補充了Allen-Bradley工業控制目錄中列出的選擇器開關的廣泛選擇。目錄中列出的選擇器開關基于最流行的兩位和三位凸輪布置，提供了一個簡短而完整的目錄編號。工業控制目錄還列出了一些特殊的三位和四位選擇器開關觸點布置。該目錄列出了（9）三位和（5）四位凸輪功能的選擇，包括各種操作器和接觸塊布置。通過將運算符前綴與接觸塊后綴連接，可以簡單地為這些單元組合目錄號。安裝選擇開關基本標準與特殊形式公告800T油密選擇開關產品數據2本出版物將幫助您選擇更廣泛的專用選擇開關。通過選擇單獨的操作員、凸輪和接觸塊，可以指定選擇器開關以滿足您的需求。這三個組件可以組合成一個簡單的目錄號。新的易于使用的“模塊化”目錄編號系統用于簡化訂購。傳統的目錄編號系統最初是為了提供緊湊的目錄編號而開發的，用于所有標準目錄列出的兩位和三位選擇器開關。參考以下示例：800T–H 2 A接觸塊后綴操作員類型
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.
