Liftmaster K1D6761-1CC Circuit Board

UL325 Replacement Logic Board for LiftMaster Commercial Openers

The LiftMaster K1D6761-1CC (now K1D6761-1CCMC) is an advanced UL325-compliant logic board engineered to secure commercial-grade swing and slide gate systems. Purpose-built for LiftMaster SL3000U/UL, CSW200U/UL, SL585U/UL, and SL595UL models manufactured after 2016, it serves as the central processor that governs gate behavior, access authorization, and entrapment protection. By enforcing monitored safety zones - particularly in the OPEN direction - it elevates system resilience against operational failures and security breaches.

Designed for maximum accountability in gated perimeters, this board also supports backward compatibility with earlier second-generation openers, provided the site is upgraded with compliant monitored photo eyes or edge sensors. Insecure or non-monitored configurations will result in non-functionality, reflecting LiftMaster’s full adherence to UL325 safety mandates.

Key Features

• Built for Critical Perimeter Control – Enforces monitored entrapment protection to prevent liability and system lockout
• UL325-Compliant Safety Logic – Requires monitored sensors in the OPEN entrapment zone to operate
• Compatible With Commercial Units – Supports SL3000U/UL, CSW200U/UL, SL585U/UL, SL595UL (2016 and newer)
• Backwards-Compatible Upgrade Path – Works with earlier models when modern safety hardware is added
• OEM Logic Core – Direct LiftMaster® replacement board ensures long-term reliability

Technical Specifications

• Model: K1D6761-1CCMC
• Also Known As: K1D9088-1CC, K1D6761-1CC
• Gate Operator Compatibility: SL3000U/UL, CSW200U/UL, SL585U/UL, SL595UL (post-2016)

Conclusion

Engineered for commercial perimeter protection systems, the LiftMaster K1D6761-1CCMC Logic Board is more than just a replacement—it is a compliance-enforcing control center designed for modern security environments. Installers and property managers must ensure monitored entrapment protection is in place or risk non-functionality. Ideal for upgrading existing gate systems to meet today’s stringent safety and liability standards.
