{"product_id":"1756-lsp-allen-bradley-safety-partner-modules","title":"1756-LSP | Allen-Bradley Safety Partner Modules","description":"\u003cp\u003eThe \u003cstrong\u003eAllen-Bradley 1756-LSP\u003c\/strong\u003e is a GuardLogix 5560 safety partner module designed for SIL 3 and Performance Level e (PL e) applications within the ControlLogix platform. Functioning as an isolated redundant co-processor alongside a primary GuardLogix controller, it provides a dual-channel architecture required to execute safety-critical logic. The module occupies a single chassis slot, connects directly via the backplane, and relies on the primary controller for configuration and key-switch operation.\u003c\/p\u003e\n\u003ch3\u003eRedundant Processing and Safety Memory Structure\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e1756-LSP\u003c\/strong\u003e operates as the secondary processing channel, mirroring safety tasks executed by compatible primary controllers, including the 1756-L61S, 1756-L62S, and 1756-L63S. It contains no standard user memory or independent task execution capability; its safety memory capacity dynamically scales based on the paired primary controller, providing 1 MB when paired with a 1756-L61S or 1756-L62S, and 3.75 MB when paired with a 1756-L63S.\u003c\/p\u003e\n\u003ch3\u003eChassis Installation and Power Requirements\u003c\/h3\u003e\n\u003cp\u003eTo meet SIL 3 requirements, the module must be installed in the slot immediately adjacent to the right of the primary controller, forming a two-slot controller pair. The module draws 1200 mA at 5.1 VDC and 14 mA at 24 VDC from the 1756 chassis backplane, dissipating 3.5 W of power. It incorporates 30 V continuous basic insulation with type-testing to 720 VDC for 60 seconds from the RS-232 port to the system backplane.\u003c\/p\u003e\n\u003ch3\u003eParameter | Specification\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1756-LSP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eSafety Partner Modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Line\u003c\/td\u003e\n\u003ctd\u003eGuardLogix 5560\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Primary Controllers\u003c\/td\u003e\n\u003ctd\u003e1756-L61S, 1756-L62S, 1756-L63S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSafety Integrity Level\u003c\/td\u003e\n\u003ctd\u003eUp to SIL 3 \/ PL e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current Draw\u003c\/td\u003e\n\u003ctd\u003e1200 mA @ 5.1 VDC, 14 mA @ 24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Dissipation\u003c\/td\u003e\n\u003ctd\u003e3.5 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThermal Dissipation\u003c\/td\u003e\n\u003ctd\u003e11.9 BTU\/hr\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Voltage\u003c\/td\u003e\n\u003ctd\u003e30 V continuous (720 VDC for 60 s type-tested)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlot Requirement\u003c\/td\u003e\n\u003ctd\u003e1 slot (2 slots total for primary and partner pair)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReplacement Battery\u003c\/td\u003e\n\u003ctd\u003e1756-BA2 (0.50 g lithium)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Chassis\u003c\/td\u003e\n\u003ctd\u003e1756-A4, 1756-A7, 1756-A10, 1756-A13, 1756-A17\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to 85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelative Humidity\u003c\/td\u003e\n\u003ctd\u003e5 to 95% (non-condensing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.50 lbs (0.68 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1756-LSP run standalone standard automation programs without a primary controller? A: No, the 1756-LSP is strictly a safety partner module that contains no standard user memory and must be paired with a primary GuardLogix controller (1756-L61S, 1756-L62S, or 1756-L63S) to function.\u003c\/p\u003e\n\u003cp\u003eQ: Where must the 1756-LSP module be installed inside the ControlLogix chassis? A: It must be installed in the slot immediately to the right of the primary GuardLogix controller to satisfy hardware pairing and SIL 3 functional safety requirements.\u003c\/p\u003e\n\u003cp\u003eQ: How is the safety memory capacity determined for the 1756-LSP? A: Memory allocation depends entirely on the paired primary unit: it provides 1 MB of safety memory when paired with a 1756-L61S or 1756-L62S, and 3.75 MB when paired with a 1756-L63S.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":53149194191128,"sku":"1756-LSP","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1756-LSP2_Cocoai_1_a350abe4-e38b-4051-a73d-4db83c317357.jpg?v=1793845134","url":"https:\/\/www.innoplcsync.com\/products\/1756-lsp-allen-bradley-safety-partner-modules","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
