SC203 access control terminal

The ZKTECO SC203 is a standalone access control terminal designed for houses, small offices and factories. It supports ID cards as standard with optional IC card capability and stores up to 30000 users and 50000 transaction records. The device combines lock control, alarm, exit button and door sensor interfaces in one unit.

Sustained operation in varied conditions

The unit operates on a 12V DC supply across temperatures from 0 °C to 45 °C and humidity between 20% and 80%. Communication runs over TCP/IP, RS232/485 and USB-Host for continuous data sync with PC software. Wiegand input and output allow master and slave configurations or connection to external control panels without interruption.

Installation and common issues

The terminal features an elegant casing with LCD display for on-device operation and audio plus LED prompts to guide users. Wiring must accommodate the electric lock, door sensor, exit button, alarm and door bell interfaces. Miswired Wiegand connections or incorrect communication settings are the typical causes of setup problems.

Questions about this item

How much power does the SC203 draw when it runs all day?

The terminal operates on a 12V DC supply and is rated for continuous use between 0 °C and 45 °C at 20%–80% humidity.

Which cables and locks must I already have to install the SC203?

You need a 12V DC power source, network cable for TCP/IP or serial cable for RS232/485, plus a third-party electric lock, door sensor, exit button and alarm.

Can the SC203 work as a slave reader to my existing Wiegand controller?

Yes, the Wiegand-in interface lets the SC203 connect to an external reader for master-slave operation, while Wiegand-out allows it to act as a reader for a control panel.
