1756-L63 Product datasheet   

1756-L63 Functional Description   

The 1756-L63 is a Programmable Automation Controller (PAC) from Allen-Bradley, designed as part of the 5560 series of Logix controllers. This model features an RS232 serial communication interface, but it also supports various communication protocols such as EtherNet/IP, ControlNet, DeviceNet, and Data Highway Plus. Additionally, by using Allen-Bradley communication adapters or third-party modules, it can integrate with other network protocols, including SynchLink and Remote I/O.

As a chassis-based controller, the 1756-L63A Guardlogix 8 MB Standard Memory Controller is installed in various ControlLogix chassis, including models like 1756-A4 and 1756-A17. It is compatible with both standard and redundant power supplies, such as the 1756-PA50 and 1756-PA75R. The controller also supports redundancy and integrated motion control, leveraging SERCOS for real-time communication and EtherNet/IP for motion over the network. The system can handle a variety of input types, including SSI, LDT, and encoder inputs for motion control.

The AB 1756-L63B ControlLogix Processor Module comes with 8 MB of user memory and 478 KB of I/O memory. For expanded storage, it can use the 1784-CF128 module, which provides 128 MB of non-volatile memory. This controller supports up to 128,000 discrete I/O and 4,000 analog I/O signals, making it ideal for large-scale applications. The controller features battery-backed RAM and supports part numbers 1756-BA1 and 1756-BATA for memory backup.

For communication, the Allen Bradley 1756-L63 has a built-in RS-232 serial port, and supports various protocols like DeviceNet, ControlNet, and EtherNet/IP. It also supports serial modules for Modbus, DH-485, and DF1 communication. The controller is built for robust industrial environments, with an operating temperature range of 0 to 60°C and shock resistance of 30g during operation.
