Description  of  1756-L63

The 1756-L63 is a processor module and controller for the ControlLogix platform which is manufactured by Allen-Bradley/Rockwell Automation. The processor comes in Series A and Series B, and it has the capability to complete 100 programs per task, perform 32 individual tasks, and complete event tasks for all event triggers. The aforementioned tasks are major controller tasks that this module can perform. The 1756-L63 weighs approximately 0.78 pounds (0.35 kilograms) and it uses the 1756-BA2 replacement battery. Like other controllers from this product line, the open-style 1756-L63 is also chassis-based and it can be installed in any slot. The 1756-L63 controller features an 8 MB memory which is available for data and logic storage. In addition to this, the module has I/O memory of 478 KB, and the users may upgrade the controller with an optional nonvolatile memory. However, it must be noted that the controller is only compatible with a 128 MB 1784-CF128 CompactFlash memory card. The controller features a basic insulation type which was tested at 720 Volts DC for 60 seconds, and it has 30 Volts continuous isolation voltage.

The controller has power dissipation of 3.5 Watts, whereas the thermal dissipation amounts to 11.9 BTU per hour. The 1756-L63 has a current draw of 1200 mA at 5.1 Volts DC, and a draw of 14 mA at 24 Volts DC. When it comes to communication, the 1756-L63 comes with a built-in RS-132 port, though the controller features other communication modules such as the ControlNet, SynchLink, and the Data Highway Plus modules to name a few. This means the users may pick and choose the most suitable communication module, and also switch the modules in accordance with their needs. The maximum vibration this processor can handle is 2 g at 10 to 500 Hertz, and its maximum operating shock is 30 g. This proves that the 1756-L63 is designed for harsh environments. The module can withstand operating temperatures of up to 60 degrees Celsius (140 degrees Fahrenheit) in an environment with 5 to 95% relative humidity.

The 1756-L63 is a Programmable Automation Controller (PAC) from Allen-Bradley. This controller is part of the earlier Logix controller version which is specifically part of the 5560 product series. This controller comes with an RS232 Serial communication interface as the primary communication port, however, this controller supports other communication protocols such as EtherNet/IP, ControlNet, DeviceNet, Data Highway Plus, Remote I/O, SynchLink and other 3rd party communication protols by installing Allen-Bradley communication adapters and encompass partner modules.

The 1756-L63 is a Chassis based controller. It is installed a variety of ControlLogix chassis such as 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17. It is also compatible for use with standard and redundant power supplies such as 1756-PA50, 1756-PA72, 1756-PA75, 1756-PB50, 1756-PB72, 1756-PB75 or 1756-PA75R, 1756-PB75R, 1756-PSCA2, respectively. It supports implementation of controller redundancy as well as integrated motion using Serial Real-Time Communication System (SERCOS), Analog options via encoder input, LDT input, SSI input and motion over Ethernet I/P network.

This controller comes with 8 MB user memory and I/O memory of 478 KB. It may be added with non-volatile memory storage via the 1784-CF128 only which has 128 MB memory size. For I/O interfacing, this controller supports up to 128,000 Discrete Input and Output and 4000 Analog Input and Output signals. It uses battery backed-up Random Access Memory (RAM) with battery part numbers of 1756-BA1, 1756-BATM, 1756-BATA for Series A controllers and 1756-BA2 Series B controllers.

The 1756-L63 controller has a built-in RS-132 serial communication port. The communication options available for this controller include the DeviceNet, ControlNet, EtherNet/IP, SynchLink, Remote I/O, Data Highway Plus, and third-party process and device networks. Serial port communications modules that this controller supports are the Modbus via logic, DH-485, DF1 radio modem, ASCII, and the DF1 full/half-duplex modules. The continuous isolation voltage of the 1756-L63 controller is 30 Volts and it has a basic insulation type. It has also been type-tested at 720 Volts DC for 60 seconds. It has a power dissipation of 3.5 W and a thermal dissipation of 11.9 BTU/hour. Its current draw at 5.1 Volts DC is 1200 mA and its current draw at 24 Volts DC is 14 mA. It has a vibration of 2 g at 10 to 500 Hertz. The 1756-L63 controller has an operating shock of 30 g and a non-operating shock of 50 g. It also has an operating temperature range of 0 to 60 degrees Celsius and a non-operating temperature range of -40 to 85 degrees Celsius. It also has a maximum surrounding air temperature of 60 degrees Celsius.
