About the Allen-Bradley 1756-L8SP

The Allen-Bradley 1756-L8SP is the GuardLogix 5580 Safety Partner Controller, which Rockwell Automation lists with an Active lifecycle status. Rockwell specifies safety memory configured to match the primary controller and an energy storage module embedded in the controller, which is non-removable. Rockwell technical data 1756-TD001 gives a current draw of 1.20 A at 5.1V DC, 5.0 mA at 1.2V DC and a power dissipation of 6.2 W. It lists an approximate weight of 0.394 kg and a slot width of 1.

What is the 1756-L8SP used for?

The 1756-L8SP works as the safety partner to the primary controller and is fitted in the chassis slot immediately to its right. Rockwell lists the 1756-A4, 1756-A4K, 1756-A7, 1756-A7K, 1756-A10, 1756-A10K, 1756-A13, 1756-A13K, 1756-A17 and 1756-A17K chassis, Series B and Series C. For SIL 2/PLd, Rockwell gives an operating temperature of 0 °C to +60 °C in a Series C chassis and 0 °C to +50 °C in a Series B chassis.
