Honeywell · Relays, Contactors & Switches

Description  The Honeywell RDI-H-R is a safety interlock switch from the Relialign™ RDI Series, designed for residential swing or hinged door applications. It operates on 24V AC/DC and features a rugged screw-terminal design with a solenoid that unlocks only when power is applied.     Technical Specifications  Condition New/Never Used Surplus Brand Honeywell Category Safety Systems Part Number RDI-H-R Subcategory Safety Interlock Switch Product Series Relialign RDI Voltage Input 24V AC/DC Contact Current (AC Max) 350 mA Contact Current (DC Max) 200 mA Termination Style Screw Terminal Contact Configuration Factory-wired for Series or Parallel (internal) Manual Override Integrated Switch Type Dual internal switches ("door closed" & "door locked") Construction Die-cast metal housing with epoxy coating Certifications ASME A17.1, UL 104 SVHC Compliance No SVHC (per 07-Jul-2017 declaration) Rated Mechanical Life >50,000 cycles Pull Force Rating >150 lbs with 10× safety margin Weight 3.55 lbs       Information About RDI-H-R The RDI-H-R is part of Honeywell’s Relialign RDI Series of electromechanical safety interlocks developed for residential swing door systems, including vertical platform lifts and similar applications. It utilizes a “mechanical lock” design that remains locked in the absence of power, enhancing occupant safety during power interruptions. The unit includes integrated switches to signal “door closed” and “door locked” states, factory-wired in either series or parallel configurations. Constructed with a die-cast metal housing, the RDI-H-R offers durability, manual override capability, and meets ASME A17.1 and UL 104 certifications for safe residential use. Key Features: Mechanical Locking Design: Prevents door opening during power failure using a power-to-unlock solenoid. Dual Safety Switches: Integrated switches provide separate "door closed" and "door locked" signals. Rugged Construction: Die-cast metal housing with electrostatic epoxy coating enhances mechanical durability. Screw Terminals: Standard terminal strip wiring for secure field connections. Low Voltage Operation: Supports 24 VAC or 24 VDC solenoid input. Contact Ratings: Rated for 350mA (AC) and 200mA (DC) switching currents. Manual Override: Allows emergency mechanical access if power is lost. No Exposed Contacts: All switch mechanisms are internally enclosed for safety. High Cycle Life: Exceeds 50,000 operation cycles under typical conditions. Certifications: Compliant with ASME A17.1 and UL 104 residential safety standards. The RDI-H-R delivers the rugged performance and locking security essential for safe and compliant residential swing door systems.
