ProdataKey R1E One-Door Access Control Expansion Board

Add control for one access-controlled door while retaining Ethernet connectivity for the controller expansion point. The ProdataKey R1E supports both OSDP and Wiegand reader interfaces, allowing it to fit installations using modern supervised reader communications as well as sites retaining Wiegand-connected reader hardware. Battery monitoring provides a dedicated status capability for deployments where backup-power condition matters to door availability. This expansion board suits physical-security installations that need to extend door coverage without changing the reader interface standard already deployed at the opening. Ethernet provides the network connection, while OSDP support addresses installations requiring the reader communication method named in the system design. Wiegand support gives integrators an interface option for compatible legacy reader connections. R1E is differentiated by its one-door controller expansion role, Ethernet connection, dual OSDP and Wiegand reader support, and battery-monitoring capability. Optional wireless and PoE++ support provide additional connection and power-path options for installations planned around those capabilities. Specify the board where the access-control design calls for a one-door expansion point rather than a multi-door controller function.
