Description
The Allen-Bradley 1756-L7SP is the Logix L7SP SIL 3 PLe Safety Partner, and Rockwell Automation lists its lifecycle status as Active Mature. According to Rockwell technical data 1756-TD001, its safety memory is configured to match the primary controller. It draws 5 mA at 1.2V DC and 800 mA at 5.1V DC, dissipates 2.5 W (8.5 BTU/hr) and weighs approximately 0.25 kg (0.55 lb). Rockwell gives the slot width as 2, with both modules needed and each one slot, and rates the module as open-style with a T4 temperature code.
Application: PLC controller
Used with: ControlLogix 1756 chassis
What is the 1756-L7SP used for?
The 1756-L7SP is the safety partner for a primary controller and is installed in the chassis slot immediately to its right. Its safety memory is configured to match the primary controller. Rockwell lists the 1756-A4 to 1756-A17 chassis (including K variants) and standard and redundant 1756 power supplies for use with it.
