Securitron -u.s. RB-4-24 Relay Board 4 Dpdt 2 Amp

Product Description

The SECURITRON -U.S. RB-4-24 is a relay board designed for access control and locking system applications. It provides four double-pole double-throw (DPDT) relay outputs, each rated at 2 amps, operating on a 24-volt input. This board allows access control panels and controllers to switch multiple independent circuits simultaneously, making it a practical expansion component in commercial and institutional door hardware installations. Locksmiths, access control technicians, and low-voltage electricians typically install this board when additional relay switching capacity is needed beyond what a primary controller provides.

The RB-4-24 is suited for use in commercial access control systems where multiple door strikes, magnetic locks, or auxiliary devices must be controlled from a single controller output. It fits into wiring enclosures alongside power supplies and control panels, serving as a relay expansion module. Typical install scenarios include multi-door access points, turnstile controls, and security system integrations where DPDT switching is required for fail-safe or fail-secure configurations.

Key Features

• Four independent DPDT relay outputs for flexible circuit switching
• 2 amp relay rating suitable for door strikes and magnetic lock loads
• 24-volt operating voltage matches standard access control power supplies
• Compact board format fits inside standard wiring enclosures
• DPDT configuration supports both normally open and normally closed wiring

Compatibility

Designed as an OEM-style relay expansion board for use in 24-volt access control and lock accessory applications.

Installation Notes

Installation is typically performed by licensed low-voltage electricians or access control technicians. De-energize the power supply and verify the circuit is dead before wiring relay inputs or outputs. Follow NEC low-voltage wiring guidelines when routing control and load conductors. Do not exceed the 2-amp relay contact rating on any output circuit.
