Access controller for small sites

The ZKTECO SC203 manages door access and time attendance for up to thirty thousand ID card holders. It stores fifty thousand transaction records and communicates over TCP/IP, RS232 or RS485. The unit suits houses, small offices and factories needing a single-door solution.

Wiegand interfaces extend the system

Wiegand input lets you add an external reader to create a master and slave pair. Wiegand output allows the SC203 to act as a reader for a separate control panel. An LCD display and audio prompts guide users, while USB-host handles template and record transfers.

Mounts directly and wires to standard hardware

Installation uses the built-in terminals for electric lock, door sensor, exit button, alarm and door bell on a twelve volt DC supply. The controller operates between zero and forty-five degrees Celsius at twenty to eighty percent humidity. No optional IC card module is included unless ordered separately.
