Von Duprin PS906-4RL Power Supply 6A - 12/24VDC Select, 4 Relay Board Integrated Logic for Controlling Security Interlocks, Auto Operators and Time Delays
The Von Duprin PS906-4RL Power Supply delivers a dependable 6 amp regulated output with field-selectable 12/24VDC operation and includes a factory-installed 900-4RL logic relay board designed for advanced access control applications. The integrated logic supports time delays, security interlocks, and auto-operator coordination, making it ideal for electrified panic devices, electric strikes, magnetic locks, and electrified trim in commercial environments. Built with universal 120–240VAC input, foldback overload protection, LED status indicators, and isolated AC monitoring contacts, the PS906-4RL provides reliable centralized power distribution with modular expansion capability. UL 294 and ULC-S318 listed, this power supply is well-suited for healthcare, education, government, and high-traffic facilities requiring intelligent relay control and dependable system performance.
