DC50 - Door controller

Print Friendly and PDF


SupraControl DC-50 is an IP-based controller designed for access control management and monitoring of operating conditions in industrial and business applications. Controller supports connection for card reader or keypad as user identification method, electric lock output with lock and door status, general purpose inputs and outputs and RJ45 SupraBUS ports for connecting up to 8 BUS sensors and detectors such as temperature, humidity, smoke, flood, vibration, particle sensor and other peripherals from Supracontrol BUS line. Controller is fully functional in Offline mode with integrated internal database with 20.000 card users with their access right and time schedules. Besides primary power supply it is possible to connnect aditional redundant power supply via Ethernet connector (passive PoE) as backup power source. The reliable network communication with server is accomplished with Ethernet/GSM Failover feature and optional GSM communication module. The DC-50 controller is monitored and managed via Supracontrol Enterprise, a centralized application for Supracontrol system monitoring available in Cloud and On-premise versions.
