PU512V1 3BSE004736R1工控模块备件
1.选择Power Base 2.选择Photohead 3.选择Mounting Assembly#60--1785 Universal，通用，360调整#60--1748重型，用于机械保护#60-2014 Flexi Mount，用于Unistrut安装在输送机导轨上#60-2083 Photoguard，#12号冷轧钢重型保护。4.选择第7页上的本质安全齐纳二极管栅选择控制图，以获取源和接收输出配置的接线图。每个控制图配置的屏障选择如下所述。对于安装，为了确保安全，每个屏障必须符合控制图纸上所示的实体参数。在选择本质安全齐纳二极管栅时，重要的是考虑栅的电阻，以确保在固有栅压降中的工作特性。电源屏障本质安全齐纳二极管屏障#897H--S120建议用于FM认证和UL认证的位置。屏障详情见第8页。或者，用户必须选择自己的电源屏障。需要注意的是，5500系列控制器必须在42DTB 5500型电源底座的+和-端子上至少具有13V DC。13V DC下的电源电流为26 mA。然后，通过以下公式确定最大势垒电阻：Rb max=Vs-13 0.026，其中：Rb max=最大势垒电阻Vs=电源13=控制用最小电压0.026=电源电流（13V DC时最大26mA）负载电源势垒本质安全齐纳二极管势垒#897H-S120建议用于FM认证和UL认证的位置。屏障详情见第8页。或者，用户可以选择自己的负载供应屏障。
1. Select Power Base 2. Select Photohead 3. Select Mounting Assembly #60--1785 Universal, general purpose, 360adjustment. #60--1748 Heavy Duty, for mechanical protection. #60--2014 Flexi-Mount, for Unistrut mounting on conveyor rails. #60--2083 Photoguard, #12 gauge cold rolled steel heavy duty protection. 4. Select Intrinsic Safety Zener Diode Barriers Select Control Drawing on page 7 for wiring diagrams of sourcing and sinking output configurations. Barrier selection is described below for each Control Drawing configuration. For installations, to ensure safety each Barrier must comply with the entity parameters indicated on the Control Drawing. In selecting the Intrinsic Safety Zener Diode Barriers, it is important to consider the resistance of the barrier to ensure operational characteristics in the midst of inherent barrier voltage drop. Power Supply Barrier Intrinsic safety zener diode barrier #897H--S120 is recommended for FM Approved and UL Listed locations. See page 8 for barrier details. Alternatively, the user must select his own power supply barrier. It should be noted that the Series 5500 control must have at least 13V DC at the + and - terminals of the power base, Type 42DTB Model 5500. The supply current at 13V DC is 26 mA. The maximum barrier resistance is then determined by the following formula: Rb maximum = Vs - 13 0.026 where: Rb max = Maximum Barrier Resistance Vs = Voltage Supply 13 = Minimum Voltage Supply to Control 0.026 = Supply Current (26mA max. at 13V DC) Load Supply Barrier Intrinsic Safety Zener Diode Barrier #897H--S120 is recommended for FM Approved and UL Listed locations. See page 8 for barrier details. Alternatively, the user may select his own load supply barrier.
