Allen-Bradley 1756-L71是ControlLogix可编程自动化控制器。它的可用存储容量为2MB，可用于用户内存，I/O内存为0.98MB。它还具有板载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。它有一个开放式机箱和内置的一（1）个2.0全速USB端口。可用的通信选项包括DeviceNet、ControlNet、EtherNet/IP、Remote I/O Data Highway Plus、第三方进程和网络以及SynchLink。

它还附带1 GB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卡留在控制器中。1756-L71控制器附带三个电容器储能模块，其中两个可拆卸。它在1.2伏直流电下的电流消耗为5毫安，在5.1伏直流电时的电流消耗是800毫安。

1756-L71控制器还具有30伏的连续隔离电压、2.5瓦的大功耗和8.5 BTU/小时的散热。它的大模拟I/O、数字I/O和总I/O分别为4000、128000和128000。它的工作温度范围为0至60摄氏度，存储温度范围为-40至85摄氏度。其周围高气温为60摄氏度，非冷凝相对湿度为5%至95%。该控制器在10至500赫兹时的振动为2G，工作震动为30G，非工作震动为50G，安装SD卡时，震动降至45G。其他控制器可能需要用户理解第 一PLC寄存器，特别是字节和位，以便开始寻址程序元素。

Allen-Bradley 1756-L71 is a ControlLogix programmable automation controller. It has 2MB of available storage, available for user memory, and 0.98MB of I/O memory. It also has an onboard 4-character alphanumeric display for easy monitoring of run time and module information as well as controller diagnostics. It has an open chassis and built-in one (1) 2.0 full speed USB ports. 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 leave the SD card in the controller. The 1756-L71 controller comes with three capacitor 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 features 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 4000, 128000 and 128000 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 non-condensing relative humidity is 5% to 95%. The controller vibrates 2G at 10 to 500 Hz, 30G at work, 50G at work, and drops to 45G when an SD card is installed. Other controllers may require the user to understand the first PLC registers, especially bytes and bits, in order to begin addressing program elements.
