PU512V2 3BUR001401R1模拟量输入模块
42DRP型接近控制允许在短距离和长距离接近应用中使用单个控制。当快门处于短距离（SR）位置时，最大操作距离为0.30 m（1 ft）。如第6页的42DRP型响应曲线所示，操作裕度的急剧下降有助于忽略接近被检测对象的背景。双开路集电极输出，一个是用于电流吸收器的NPN开路集电极，另一个是提供电流源的PNP开路集电极。因此，这些控制提供了同时连接到继电器负载或光耦合器驱动器和TTL逻辑输出的机会。连接图见第7页。电源底座类型42DRU、42DRP和42DRA本质安全型5500和5700光电头只能插入适用于13…29.5V DC电压输入的端子底座类型42DTB 5500。42DTB 5500型终端底座允许用户直接将输入和输出连接到控制器，从而消除了单独接线盒的需要。接线连接采用易于接线的压力型端子，带有重要的光纤和飞线，不可能悬浮在空气中，但会聚集在机器周围或照明设备上，热量、火花或热金属会点燃它们。灵敏度调整光/暗开关可见对准指示器短程远程快门（仅适用于42DRP）PNP和NPN输出电路3 2 1（+）（-）SENS LO HI DK LT双向时间延迟O N O F F低-高灵敏度开关4罗克韦尔自动化出版物42DR-IN001B-EN-P-2016年5月本质安全传感器非旋转夹具，安装在螺钉上，最多可处理两个#14 AWG电线。订购说明
ype 42DRP proximity control permits the use of a single control for both short- and long-range proximity applications. With the shutter in the short range (SR) position, the maximum operating distance is 0.30 m (1 ft). The very sharp drop off in operating margin as shown in the Type 42DRP response curve on page 6 helps to ignore backgrounds that are close to the object being detected. The dual open collector outputs, one an NPN open collector for current sink and the other a PNP open collector to provide current source, are included in all Type 42DR controls to maximize customer logic interconnection capabilities. Therefore, these controls provide the opportunity for simultaneous connection to relay loads or optocoupler drives and TTL logic outputs. See page 7 for connection diagrams. Power Base Type 42DRU, 42DRP, and 42DRA Intrinsically Safe models 5500 and 5700 Photoheads can be plugged only into a terminal base Type 42DTB Model 5500 suitable for voltage inputs of 13…29.5V DC. The Type 42DTB Model 5500 Terminal Base allows the user to make incoming and outgoing connections directly to the control thereby eliminating the need of a separate junction box. Wiring connections are made to easy-to-wire pressure type terminals with IMPORTANT Fibers and flyings are not likely to be suspended in the air, but can collect around machinery or on lighting fixtures and where heat, a spark or hot metal can ignite them.
