The Allen-Bradley 1756-LSP is a safety partner module designed for the GuardLogix 5570 programmable automation controller (PAC) platform by Rockwell Automation.
Acting as a co-processor, it provides dedicated safety processing functions and includes integrated memory that mirrors the safety memory of the primary controller, typically ranging from 1 MB to 3.75 MB.
The 1756-LSP installs in a ControlLogix chassis directly beside the primary controller and draws approximately 1200 mA at 5.1 VDC and 14 mA at 24 VDC from the backplane.
It ensures reliable and synchronized safety control operations across GuardLogix systems, supporting high-integrity safety applications.
