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

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

The Allen-Bradley 1756-LSP Series B GuardLogix 55LSP Safety Partner Processor is an integral component of the GuardLogix 5560 series, designed to work alongside primary safety controllers such as the 1756-L61S, 1756-L62S, and 1756-L63S. This module enhances system redundancy and ensures the integrity of safety functions within industrial automation systems.

Key Features

• Safety Integration: Functions as a safety partner module, providing redundancy and isolating safety functions from standard logic processing.
• Memory Configuration: Mirrors the safety memory of the paired primary controller—1 MB with 1756-L61S/L62S and 3.75 MB with 1756-L63S.
• Installation: Occupies a single slot immediately to the right of 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 LED indicators to provide real-time status updates and facilitate troubleshooting.
• Connectivity: Features RS-232 port isolation tested at 720 VDC for 60 seconds and includes 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.
