>>>>>型号:1756-L71 可编程自动化控制器 配有三个电容储能模块
【功能描述】
Allen-Bradley 1756-L71是ControlLogix可编程自动化控制器。它有2 MB的用户内存可用存储空间和0.98 MB的I/O内存。它还有一个板载4字符字母数字显示器，便于监控运行时间和模块信息以及控制器诊断。它有一个开放式外壳和一个内置的2.0全速USB端口。可用的通信选项包括DeviceNet、ControlNet、EtherNet/IP、远程I/O Data Highway Plus、第三方过程和网络以及SynchLink。它还配有1 GB的非易失性内存，但您可以使用1784-SD2将其升级到2 GB。建议将SD卡安装在控制器中。
1756-L71控制器配有三个电容储能模块，其中两个是可拆卸的。它在1.2伏DC下的电流消耗为5毫安，在5.1伏DC下的电流消耗为800毫安。1756-L71控制器还具有30伏的持续隔离电压、2.5瓦的最大功耗和8.5 BTU/小时的热耗散。它的最大模拟I/O、数字I/O和总I/O分别为4，000、128，000和128，000。它的工作温度范围为0至60摄氏度，储存温度范围为-40至85摄氏度。它周围的最高气温为60摄氏度，相对湿度为5%到95%。该控制器在10到500赫兹时的振动为2G，工作时的冲击为30G，非工作时的冲击为50G，安装SD卡后下降到45G。其他控制器可能要求用户理解第一PLC寄存器的具体字节和位，以便开始寻址程序元素。对于1756-L71，用户只需插入一个程序单元，并选择I/O物理连接的逻辑通道。在其它PLC中，用户可能会发现需要将一个寄存器移到另一个寄存器，以启动转换和处理，从而获得模拟数据。该控制器只需要用户找到I/O信号物理终止的逻辑通道。

【英文介绍】
Allen-Bradley 1756-L71 is a ControlLogix programmable automation controller. It has 2 MB of user memory available storage and 0.98 MB of I/O memory. It also has an onboard 4-character alphanumeric display for easy monitoring of uptime and module information as well as controller diagnostics. It has an open case and a built-in 2.0 full speed USB port. Available communication options include DeviceNet, ControlNet, EtherNet/IP, Remote I/O Data Highway Plus, third-party processes and networks, and SynchLink. It also comes with 1 GB of non-volatile memory, but you can upgrade it to 2 GB with the 1784-SD2. You are advised to install the SD card in the controller.
The 1756-L71 controller is equipped with three capacitive energy storage modules, two of which are removable. It has a current consumption of 5 mA at 1.2 volts DC and 800 mA at 5.1 volts DC. The 1756-L71 controller also has a continuous isolation voltage of 30 volts, a maximum power consumption of 2.5 watts, and a heat dissipation of 8.5 BTU/ hour. Its maximum analog I/O, digital I/O and total I/O are 4,000, 128,000 and 128,000, respectively. It has an operating temperature range of 0 to 60 degrees Celsius and a storage temperature range of -40 to 85 degrees Celsius. The maximum temperature around it is 60 degrees Celsius and the relative humidity is 5 to 95 percent. The controller has a vibration of 2G at 10 to 500 Hz, a shock of 30G when working, 50G when not working, and a drop to 45G after the SD card is installed. Other controllers may require the user to understand the specific bytes and bits of the first PLC register in order to begin addressing program elements. For 1756-L71, the user simply plugs in a program unit and selects the logical channel where I/O is physically connected. In other PLCS, users may find it necessary to move one register to another in order to initiate conversion and processing to obtain analog data. The controller only requires the user to find the logical channel where the I/O signal is physically terminated.
