Technical Specifications for 1756-lsp

About 1756-lsp

The 1756-LSP controller is a GuardLogix and ControlLogix controller from Allen-Bradley. It has a built-in serial port for communication with other devices. The 1756-LSP controller module can handle up to 250 controller connections at a single time. The non-volatile memory card that it is compatible with is the CompactFlash memory card. The 1756-LSP controller module comes with LEDs that act as status indicators which can let the users know whether the module is powered on or not and if there are any errors or malfunctions in the system. Because it is a member of the GuardLogix controller product line within the broader ControlLogix controller series, the 1756-LSP controller module is a safety module that is designed to handle specific safety-related applications in industrial systems.

The Allen-Bradley 1756-LSP GuardLogix safety controller module is best suited for Ple safety applications and for SIL 3 safety applications. It is meant to be used as the safety partner device within a complete GuardLogix system where it will operate alongside a primary GuardLogix controller module. In the GuardLogix system, the 1756-LSP controller module must be installed directly to the right of the primary controller module, and it must also have the same firmware revisions as the primary controller module that it is partnering with. The 1756-LSP controller module ships with a battery known as the 1756-BA2 battery. This battery is a lithium battery, and when it eventually runs out, it can be replaced. The 1756-BA2 battery is used by the 1756-LSP safety controller to backup the contents of its 

CompactFlash memory in case of a power failure.
