TECHNICAL SPECIFICATIONS

The Allen-Bradley 1756-L71 ControlLogix PAC (Programmable Automation Controller) is capable of supporting up to 100 axes and is optimized for the control of high-performance motion drives via EtherNet/IP or SERCOS interfaces. It has 2 MB of user memory storage available. Additionally, it features a built-in 4-character alphanumeric display for quick monitoring of module and run-time data and controller diagnostics.

It contains an installed full-speed USB 2.0 connector and an open-style enclosure. This controller's USB interface enables firmware flashing, programming, and setup. One or more of the connection options include EtherNet/IP (Ethernet Industrial Protocol), ControlNet, Data Highway Plus (DH+), DeviceNet, SynchLink, and third-party systems and processes.

The non-volatile memory is 1 GB by default. However, you may increase it to 2 GB by purchasing the 1784-SD2. It is advised to keep the SD card in the controller after installation.

Two of the three capacitor energy storage modules that come with the 1756-L71 Programmable Automation Controller are detachable. It uses 800 mA at 5.1V dc and 5 mA at 1.2V dc in current consumption.

Additionally, it dissipates a maximum of 2.5 Watts of electricity and 8.5 BTU of heat each hour. Additionally, it provides a 30V continuous isolation voltage. It can operate in temperatures between 0 and 60 °C and stored at temperatures between -40 and 85 °C. It has a maximum ambient air temperature of 60 °C and a relative humidity range of 5% to 95% without condensation.

The controller has a 30G shock while active, a 50G shock when not operating, and a 2G vibration at 10...500 Hz that falls to 45G with an SD card inserted. To begin addressing program components, other controllers may first demand the user to comprehend PLC (Programmable Logic Controller) registers.

After inserting a program component into the device, the user of the 1756-L71 PAC selects the logical channel to which the input and outputs are physically attached. Faster software familiarization and a rapid start are made possible by this feature. In other PLCs, the user could discover that to start conversion and processing and obtain the analog data, one must transfer a register to another. The user of this controller has to identify the logical channel on which the I/O signal ends physically.

The industrial and process automation industries' control requirements are well suited to this PAC module, which is best suited for large to medium-sized automation systems.

This controller is chassis-based. A specific ControlLogix chassis is required to install the module. The 1756-A7, 1756-A10, 1756-A4K, 1756-A10K, 1756-A4, 1756-A13K, 1756-A17, 1756-A7K, 1756-A13, and 1756-A17K are among the chassis that are compatible.
