The Allen-Bradley 1756-LSP is a GuardLogix safety partner controller. It has 250 connections but it does not have any user memory for standard tasks. Its safety memory depends on the memory of the corresponding primary controller. Its main purpose is to provide a redundancy, a second channel that is isolated for the system's safety-related functions. This controller has current draws of 1200 mA at 5.1V DC and 14 mA at 24V DC. Its power dissipation is 3.5 W and its thermal dissipation is 11.9 BTU/hr.
