CDVI CA-A460-P Centaur Relay Expansion Module

When you need more outputs for locks, alarms or auxiliary devices, the CDVI CA-A460-P Relay Expansion Module delivers fast, reliable expansion for access control and security systems. This CDVI control panel module adds seven Form C relays to the CT-V900-A controller and can be installed up to 1,220 m (4,000 ft.) from the panel over the RS-485 E-BUS, ideal for remote doors, gates or distributed I/O in surveillance and building automation deployments. Up to two modules can be added per controller for a total of 16 relays, letting integrators scale installations without complex rewiring.

Designed for professional security and monitoring applications, the CA-A460-P runs on 12 VDC, provides per-relay status LEDs for rapid diagnostics, and includes a 24-hour anti-tamper input plus communication-failure output for robust site supervision. The metal housing and optional removable terminals simplify installation and maintenance in commercial environments.

Use the CA-A460-P to expand control points across access control, alarm integration, and remote monitoring projects. Contact your reseller or order today to add flexible, remotely placed relay control to your CDVI CT-V900-A installations.
