电源过载
1V DC时120 mA 24V DC时2 mA将此电流/功率值（0.66 W）添加到机箱中所有其他模块的要求中，以防止电源过载。安装模块您可以在机箱通电时安装或卸下模块。1.将电路板与机箱顶部和底部导轨对齐。警告当您在背板电源接通时插入或卸下模块时，可能会发生电弧。这可能会导致危险场所装置发生爆炸。在继续之前，确保电源已断开或该区域无危险。重复的电弧会导致模块及其配合连接器上的触点过度磨损。触点磨损可能会产生电阻，从而影响模块工作。印刷电路板20861 MControlLogix 32点DC（10…31.2V）输入模块，系列B 9 2.将模块滑入机箱，直到模块锁定卡舌发出咔嗒声。锁紧凸耳20862-M键合模块和可拆卸接线板/接口模块使用楔形键合凸耳和U形键带，以防止将错误的导线连接到模块。键入模块上对应于RTB上未锁定位置的位置。例如，如果您键入模块上的第一个位置，请将RTB上的第一位置保持不变。1.如图所示，插入U形带，以键控模块。
Synthetic material substitutes
Synthetic material substitutes for equipment unsuitable for use in Category I and Category II environments. ControlLogix 32 point DC (10... 31.2V) input module, B series 7 publication 1756-IN027F-EN-P-2008 October About the module ControlLogix I/O module installed in the ControlLogix chassis, a removable terminal block (RTB) or 1492 interface module (IFM) is required (1) to connect all field side patch cords. Before you begin, you should: Identify the module components before installing the I/O modules. Pay attention to the power requirements. Module Components You received these components in your order: 1756-IB32 Module Removable Terminal Block (RTB) Door Label If you did not receive these components, please contact your local dealer or Rockwell Automation sales office. The module uses one of the following RTBs: 1756-TBCH 36 position cage clamp RTB 1756-TBS6H 36 position spring clamp RTB uses extended depth cover (catalog number 1756-TBE) for large size wiring or applications requiring additional wiring space. When using IFM, refer to the attached documentation to connect the wiring. (1) The ControlLogix system has been agency certified using only ControlLogixRTB (for example, 1756-TBCH, 1756-TBNH, 1756-TB SH, and 1756-TBS6H). Any application that requires agency certification of the ControlLogix system by using other wiring termination methods may require application specific approval from the certification agency. Important: Before installing the module, you should: Install and ground the 1756 chassis and power supply. Order and receive RTBs or IFMs and their components for your application. 8 ControlLogix 32 point DC (10... 31.2V) input module, B series publication 1756-IN027F-EN-P-2008 October Power supply requires this module to receive power from the 1756 chassis power supply, requiring two power supplies for the ControlLogix backplane.
Power overload
120 mA at 1V DC 2 mA at 24V DC Add this current/power value (0.66 W) to the requirements of all other modules in the chassis to prevent power overload. Installing Modules You can install or remove modules when the chassis is powered on. 1. Align the circuit board with the top and bottom rails of the chassis. Warning When you insert or remove a module while the backplane is powered on, an arc may occur. This may lead to explosion of devices in hazardous areas. Before continuing, make sure that the power supply is disconnected or that the area is not dangerous. Repeated arcing can cause excessive wear of the contacts on the module and its mating connectors. Worn contacts may cause resistance which may affect the operation of the module. Printed circuit board 20861 MControlLogix 32 point DC (10... 31.2V) input module, series B 9 2. Slide the module into the chassis until the module locking tab clicks. Locking lug 20862-M bonding module and removable terminal block/interface module use wedge bonding lug and U-shaped key strip to prevent wrong wire from connecting to module. Type the position on the module that corresponds to the unlocked position on the RTB. For example, if you type the first position on the module, leave the first position on the RTB unchanged. 1. As shown in the figure, insert the U-shaped belt to key the module.
