SC203 Access Control Terminal

The SC203 is a standalone RFID time-attendance and door-access controller designed for small offices, homes and factories. It supports ID cards as standard with optional IC card reading and stores up to 30000 users and 50000 transaction records. Communication options include TCP/IP, RS232, RS485 and USB-Host for PC software management or offline data transfer.

Ideal for Simple Sites Not for Multi-Door Systems

This unit suits locations that need a single-door controller with built-in lock, alarm, exit-button and door-sensor interfaces. It is not intended for installations that require multi-door coordination, advanced anti-tailgating logic or integration with enterprise directory services beyond the listed Wiegand and TCP/IP links.

30000 ID Card Capacity Decides Fit

The 30000 ID card capacity is the key figure that determines whether the SC203 matches your workforce size. If your site needs more enrolled users or a larger transaction log, you will need a different controller; otherwise this capacity covers typical small-office and factory deployments.

Questions about this item

How do I verify the SC203 is working correctly after installation?

Check the LCD display for normal operation and listen for audio prompts when presenting an ID or optional IC card; the LED feedback will confirm a successful read and door release.

What comes in the box and what must be purchased separately?

The controller includes interfaces for an electric lock, door sensor, exit button, alarm and door bell; the lock, sensor, button, alarm hardware and proximity cards are not included and must be sourced separately.

Which card capacity version should I choose for my site?

The SC203 supports up to 30000 ID cards and stores 50000 transactions; select this model if your user count fits within 30000, otherwise a higher-capacity unit is required.
