Schlage Electronics 9004RL 4-relay Board

Product Description

The SCHLAGE ELECTRONICS 9004RL is a 4-relay board with integrated logic designed for electronic access control applications. It provides switching and control functions for door hardware, electric strikes, magnetic locks, and other access-controlled devices in commercial and institutional security systems. The board combines multiple relay outputs with onboard logic processing, reducing the need for separate control modules and simplifying panel wiring. Licensed security system integrators and low-voltage electricians are the typical installers. Dimensions are 7.2 inches in length, 4.4 inches in width, and 2.8 inches in height, with a total weight of 0.5 pounds.

The 9004RL is suited for commercial buildings, multi-family residential properties, and institutional facilities where controlled access at multiple door points is required. It is installed within access control panels or enclosures as part of a broader electronic access control system, supporting applications where relay-switched outputs are needed to trigger door hardware or auxiliary devices at each controlled opening.

Key Features

• Four relay outputs with integrated logic for streamlined access control wiring
• Compact form factor at 7.2 x 4.4 x 2.8 inches for panel or enclosure mounting
• Lightweight construction at 0.5 pounds for easy handling and installation
• Combines relay switching and onboard logic in a single board, reducing component count
• Suitable for commercial, multi-family, and institutional access control deployments

Compatibility

Designed as an OEM-style replacement or expansion relay board for commercial electronic access control systems requiring four relay outputs with integrated logic.

Installation Notes

Installation should be performed by a licensed low-voltage electrician or certified access control integrator. De-energize the access control panel completely before handling the board or making any wiring connections. Follow NEC low-voltage wiring guidelines and all applicable local codes when routing and terminating control wiring. Verify relay output ratings against the connected door hardware specifications before powering the system.
