Built-in communication 1 USB port
The Allen-Bradley 1756-L71 is a ControlLogix programmable automation controller. It has 2 MB of user memory and 0.98 MB of I/O memory. It also features an onboard 4-character alphanumeric display for easy monitoring of runtime and module information as well as controller diagnostics. It has an open housing 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 a 1 GB non-volatile memory, but you can upgrade it to 2 GB with the 1784-SD2. You are advised to keep 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 V DC and 800 mA at 5.1 V 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 4,000, 128,000 and 128,000, respectively. The operating temperature of this product is 0 to 60 degrees Celsius and the storage temperature is -40 to 85 degrees Celsius. It has a maximum ambient air temperature of 60 degrees Celsius and a non-condensing relative humidity of 5 to 95%. The controller has 2G vibration at 10 to 500 Hz, 30G operating shock, and 50G non-operating shock, dropping to 45G when SD card is installed. Other controllers may require the user to first understand the PLC registers, especially bytes and bits, in order to begin addressing program elements. With the 1756-L71, the user simply inserts a program element and selects the logical channel that physically connects the I/O. In other PLCS, users may find it necessary to move one register to another to initiate conversion and processing, just to get analog data. The controller only needs the user to find the logical channel to which the I/O signal is physically terminated.
