CT-V900-A – 2-Door Controller

The CT-V900-A is at the heart of every Centaur access control system. The Centaur Server, hardware expansion modules, multi-purpose inputs, card readers, keypads and outputs are connected directly to the CT-V900-A. Multi-controller systems are networked via the RS-485 communication bus (or using the optional CA-ETHER-A over a TCP/IP network). Distributed database architecture allows each controller to make split-second decisions without needing to communicate with the Centaur server.

Lightning-quick, robust and remarkable stability make the CT-V900-A the professional’s choice.
