Allen-Bradley 1756-LSP Guardlogix 55LSP Safety Partner Processor Module Series B

Allen-Bradley 1756-LSP GuardLogix 55LSP Safety Partner Processor Module Series B

The Allen-Bradley 1756-LSP is a Safety Partner Processor Module designed to work in conjunction with primary GuardLogix controllers, such as the 1756-L61S, 1756-L62S, and 1756-L63S. This pairing ensures compliance with Safety Integrity Level (SIL) 3 and Performance Level (PL) e standards, providing a robust solution for safety-critical applications.

Key Features

• Safety Integration: Operates alongside primary GuardLogix controllers to deliver SIL 3 and PLe-rated safety functionality.
• Memory Configuration: Mirrors the safety memory of the associated primary controller—1 MB with 1756-L61S/L62S and 3.75 MB with 1756-L63S.
• Installation: Occupies a single slot immediately adjacent to the primary controller within a ControlLogix chassis, ensuring seamless integration.
• Power Requirements: Draws 1200 mA at 5.1V DC and 14 mA at 24V DC, with a power dissipation of 3.5 W and thermal dissipation of 11.9 BTU/hr.
• Diagnostic Indicators: Equipped with front-panel LEDs to provide real-time status updates and facilitate troubleshooting.
• Connectivity: Features an isolated RS-232 port tested at 720 VDC for 60 seconds and supports CompactFlash nonvolatile memory for data retention.
• Environmental Resilience: Operates within a temperature range of 0–60 °C, withstands shocks up to 30 g, vibrations up to 2 g, and functions in humidity levels up to 95% non-condensing.
