1756-L71控制器还具有30伏的连续隔离电压、2.5瓦的最大功耗和8.5 BTU/小时的散热。它的最大模拟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。其周围最高气温为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。

对于1756-L71，用户只需插入一个程序元素并选择I/O物理连接的逻辑通道。在其他PLC中，用户可能会发现需要将一个寄存器移动到另一个寄存器，以启动转换和处理，从而获得模拟数据。该控制器仅要求用户找到I/O信号物理终止的逻辑信道。

该控制器是现代Logix控制器平台的一部分，该平台被分类为可编程自动化控制器（PAC）。该PAC产品系列非常适合于中大型自动化要求，尤其适用于工厂和过程自动化行业的控制要求。

1756-L71主要具有2MB用户内存和0.98MB I/O内存。它还附带1784-SD1安全数字（SD）存储卡，容量为1 GB非易失性存储器，可通过更换1784-SD2卡升级为2GB。该控制器可处理多达128000个离散输入和输出信号以及4000个模拟输入和输出。

作为一款现代控制器，1756-L71不使用电池来保存随机存取存储器（RAM）或易失性存储器的内容，而是配备了目录号为756-ESMCAP或1756-ESMCAPK的储能模块。该能量存储模块是基于电容器的可拆卸型。

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.

For 1756-L71, the user simply inserts a program element 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.

The controller is part of the modern Logix controller platform, which is classified as a Programmable Automation Controller (PAC). The PAC product family is well suited for medium to large automation requirements, especially for the control requirements of the factory and process automation industry.

The 1756-L71 mainly has 2MB of user memory and 0.98MB of I/O memory. It also comes with a 1784-SD1 secure digital (SD) memory card with a capacity of 1 GB of non-volatile memory, which can be upgraded to 2GB by replacing the 1784-SD2 card. The controller can process up to 128,000 discrete input and output signals and 4,000 analog inputs and outputs.

As a modern controller, the 1756-L71 does not use a battery to hold the contents of random access memory (RAM) or volatile memory, but is equipped with an energy storage module with the catalog number 756-ESMCAP or 1756-ESMCAPK. The energy storage module is a detachable type based on a capacitor.
