ZKTECO SC203+IC Access Controller

The ZKTECO SC203+IC is a standalone RFID access controller designed for door entry and time attendance. It supports both ID and optional IC cards with a capacity of 30000 users and stores up to 50000 transaction records. The unit features an LCD display for local operation and provides full door lock control including interfaces for electric lock, door sensor, exit button and alarm.

Suits small offices and factories needing

This device fits sites that require TCP/IP, RS232 or RS485 connectivity to a central PC for enrolment and log collection. The Wiegand input allows a master and slave reader setup while Wiegand output lets the unit act as a reader for a separate control panel. Buyers who need wireless connectivity or built-in biometric verification should look at something else.

Mounts on a wall with screw terminals for power

Installation uses a 12V DC supply and standard low-voltage wiring for lock, sensor, button and alarm connections. The USB-host port enables offline data transfer when network access is unavailable. Common issues include incorrect Wiegand polarity between master and slave units and exceeding the 45 °C operating temperature limit in unventilated enclosures.

Questions about this item

What lock, sensor, button and alarm hardware must already be wired for the SC203+IC to control a door?

The controller provides terminals for a third-party electric lock, a door sensor, an exit button, an alarm output and a door bell, so each of those devices needs to be present and wired before the unit can operate the entrance.

Will the SC203+IC work as a Wiegand slave reader alongside an existing access panel that only accepts Wiegand input?

Yes, the Wiegand-out interface lets the SC203+IC connect to a control panel as a reader, so it can sit downstream of an older panel that expects Wiegand data.

After wiring and power-up, what on the device confirms the SC203+IC is communicating with the network and ready to enrol cards?

The LCD display shows menu operation and status, while audio prompts and LED feedback guide the user; successful TCP/IP or RS232/485 link and card enrolment can be verified on-screen and via the PC software.
