Aiphone AC-IOE AC Series 8-Floor 8-Port IO Expander Board without Enclosure, requires ACS-ELV or ACS-IO Starter Kit

Scale your access control and security infrastructure without replacing core hardware using the Aiphone AC-IOE AC Series 8-Floor IO Expander Board. This access control module adds eight dry-contact inputs and eight solid-state relay outputs per board, enabling you to expand floors or ports cost-effectively for multi-tenant buildings, campuses, or distributed facilities. Communicating over RS485 (or optional PRS-Strip), the AC-IOE delivers reliable wired connectivity for surveillance and monitoring integrations and supports up to seven expanders on an ACS-IO or ACS-ELV starter kit.

Designed for integrators and IT/security teams, the AC-IOE draws 12V DC from the main board to reduce extra power runs and installs directly into indoor control panels. UL/ULC (UL 294/ULC 5319-5) listing ensures compliance with commercial security standards, giving peace of mind for critical access deployments. Whether you’re upgrading an existing system or staging phased deployments, this compact, TAA- and NDAA-compliant module streamlines installation and future growth. Add the Aiphone AC-IOE to your ACS-IO or ACS-ELV starter kit to expand monitoring and access control capacity quickly—order now to simplify your next security upgrade.
