Von Duprin PS914-4RL Base Power Supply 4A @ 12/24 VDC Field Selectable, 4 Relay Board Integrated Logic

Von Duprin PS914 Base Power Supply 4A  @ 12/24 VDC Field Selectable, 4 Relay Board Integrated - (PS873 Replacement)

Model - PS914-4RL: 4 relay distribution board with logic is field configurable for time delay function, auto operator, security interlock

  Von Duprin power supply and option board products were designed to meet the specific requirements of electrified fire exit devices.

Installation is simplified by utilizing a flat mounting design and polarized locking connectors for option boards. This design eliminates the need for racks and side connectors. The flat mounting of the option boards also provides for easier access to the terminal blocks for connection of electrified devices (such as electrified panic devices, strikes, card readers, etc.).

Common to the line of PS900 Series power supplies is a constant output rating at both 12v and 24v settings, universal 120 VAC to 240 VAC input, and polarized option board connectors. New fire alarm interface board mounting allows outputs to be configured as switched (power cut) or unswitched (power continues) when signal is provided.
