SC203 Access Control Terminal

The ZKTeco SC203 is a TCP/IP time attendance and door access control terminal designed for houses, small offices and factories. It supports ID cards as standard with IC card as an optional upgrade. The device provides a full door lock control system with interfaces for electric lock, door sensor, exit button, alarm and door bell.

Verify Power and Wiring Requirements

The unit requires a 12V DC power supply and operates between 0 °C and 45 °C with 20% to 80% humidity. Confirm your site has the necessary cabling for TCP/IP, RS232 or RS485 communication and for the Wiegand input and output connections. Ensure the installation location can accommodate the LCD display and keypad for on-device operation.

Upgrade from Standalone Readers

The SC203 replaces basic standalone readers by adding networked TCP/IP, RS232 and RS485 communication plus USB-host for data transfer. It supports 30000 ID card capacity and 50000 transaction records with anti-passback and SMS functions. The Wiegand interfaces allow master and slave configurations or connection to a control panel, making the jump worthwhile when centralised management and expanded capacity are needed.

Questions about this item

Does the SC203 terminal include the electric lock, door sensor and exit button, or must they be purchased separately?

The unit provides interfaces for a third-party electric lock, door sensor, exit button, alarm and door bell; those components are not included and must be sourced separately.

Should I choose the standard ID card version or the optional IC card version for the SC203?

The SC203 ships with ID card support as standard; IC card capability is an optional function that can be added if your site requires it.

What does the 30,000 ID card capacity mean for daily operation of the SC203?

It allows up to 30,000 enrolled users to be stored on the terminal, with 50,000 transaction records kept before older logs are overwritten.
