Overview
The Suprema Secure I/O 2 (SIO2) is a compact door module for one door. When a Suprema reader is mounted outside, the lock relay sits in the reader. SIO2 moves that relay to the secure side of the door, so tampering with the reader cannot open the lock.
Is it right for you?
Choose it for any single door where the Suprema reader or terminal is exposed, such as an entrance or an outdoor gate. It talks to the reader over encrypted RS-485. It replaces the earlier Secure-IO.
