CT-V900-A
2-Door Controller
Overview
The CT-V900-A is the core component of every Centaur access control system. It integrates with the Centaur Server, hardware expansion modules, multi-purpose inputs, card readers, keypads, and outputs. Multi-controller systems are networked via the RS-485 communication bus or optionally via TCP/IP with the CA-ETHER-A. Its distributed database architecture allows each controller to make immediate decisions without needing to communicate with the Centaur server, ensuring high-speed, reliable performance.
