Suprema Secure Module SIO2 Compact Single Door I/O
SIO2, interface-module, 1 Form C Relay, RS-485 OSDP
Suprema Secure Module (SIO2) is an ultra-compact single door I/O module designed to prevent door lock spoofing by placing the door lock relay on the secure inside of the facility, communicating via encrypted RS-485 OSDP V2.
Product Overview
SIO2 enhances door security by physically decoupling the exterior reader from the lock relay. Installed on the secure interior side of the wall, it receives encrypted trigger commands from Suprema readers over RS-485, neutralizing wire-bypassing and lock-picking attempts.
