Overview

SecureIO 2 is Suprema's compact secure I/O module, purpose-built to add encrypted door control to any CoreStation or OSDP V2-compliant access controller deployment. Connected via RS-485 OSDP V2, SecureIO 2 provides secure relay output for electric strikes and electromagnetic locks alongside two supervised inputs for door sensors and request-to-exit buttons. At just 36 × 65 × 18 mm and 37 g, SecureIO 2 mounts inside any door frame or access panel — extending CoreStation's encrypted access control perimeter to doors that require physical separation of the reader and the lock relay.

Key Features

OSDP V2 encrypted communication

RS-485 OSDP V2 slave interface ensures all door control commands are AES-encrypted end-to-end between controller and relay.

Compact panel-mount design

36 × 65 × 18 mm form factor mounts inside any door frame, access panel or enclosure alongside cabling — zero wasted space.

Supervised inputs

2 supervised input channels for door contacts, REX buttons or alarm sensors — with tamper detection on all inputs.

1 relay output

1 relay output drives electric strikes, electromagnetic locks or door latches — controlled via encrypted CoreStation commands.
