SC203 Access Controller

The ZKTECO SC203 is a TCP/IP networked access controller designed for door entry and time-attendance tracking. It supports up to 30000 ID card users and stores 50000 transaction records on the device. Communication options include TCP/IP, RS232, RS485 and a USB host port for data transfer. The unit integrates lock control, door sensor, exit button, alarm and door bell interfaces in a single housing.

Small Sites Needing Standalone Control

This controller suits small offices, houses or factories that want a self-contained system with an LCD display for local operation and optional PC software management via network or serial links. It also works as a Wiegand reader for a larger panel or as a master unit with slave readers. Buyers who need integrated biometric verification, Wi-Fi connectivity or PoE power should look at other models because those features are not included.

Straightforward Wired Installation

Mount the unit, connect 12 V DC power and wire the lock, sensor, exit button and alarm to the labelled terminals. Network setup uses the built-in TCP/IP port; RS232 or RS485 are available for legacy cabling. Common issues include mismatched Wiegand format between master and slave devices and incorrect door-sensor polarity preventing anti-passback from working. The operating range is 0 °C to 45 °C at 20 % to 80 % humidity.
