eSSL SC-405 – Standalone RFID Access Control Machine & Time Attendance Terminal
The eSSL SC-405 access control machine is a compact, standalone RFID terminal that combines time attendance tracking with door access control in one cost‑effective device. Supporting 125kHz EM proximity cards and PIN codes, it delivers fast (≤0.1 sec), secure, and contactless authentication. With a built‑in relay for direct lock control, 30,000 card capacity, 50,000 transaction logs, and TCP/IP + USB communication, the SC-405 is the ideal solution for offices, factories, schools, and residential buildings.
The eSSL SC-405 is a standalone RFID access control and time attendance terminal that combines a card reader, keypad, and door controller in a single unit. It reads 125kHz EM proximity cards and accepts PIN‑based authentication, transmitting the user ID to the built‑in relay for direct lock control – no external controller needed. All user credentials (up to 30,000 cards) and attendance logs (50,000 events) are stored locally on the device, making it a cost‑effective, easy‑to‑install solution for small to medium‑sized facilities.
The SC-405 features a 2.0‑inch colour TFT display with an intuitive graphical user interface, a backlit 4 × 4 keypad, and both green/red LED indicators for clear access feedback. It supports multiple verification methods – card only, PIN only, or card + PIN – allowing you to choose the appropriate security level for each user group. The device connects to a PC via TCP/IP (Ethernet), RS485, or USB for data export, configuration, and software updates. With its built‑in relay, door sensor input, exit button support, and anti‑passback logic, the SC-405 is a complete, all‑in‑one access control machine for single‑door installations.

🔑 Key Features – eSSL SC-405 Access Control Machine
✅ 30,000 Card Capacity & 50,000 Transaction Logs Large‑scale user and event storage for small to medium enterprises. Maintain a complete attendance and access audit trail without frequent downloads.
✅ ≤0.1 Sec Identification Speed High‑speed 32‑bit ARM microprocessor for instant card reading – employees can tap and go without waiting, reducing queuing during peak hours.
✅ 2.0" Colour TFT Display + 4×4 Keypad Clear, user‑friendly graphical interface with backlit keypad. Employees can view their last punch time, check schedules, and receive system notifications directly on the device.
✅ Built‑In Relay for Lock Control The SC-405 includes a built‑in relay (≤3 A) to directly control electric locks, magnetic locks, and strikes – no external controller required for single‑door installations.
✅ Multiple Communication Interfaces Standard TCP/IP (Ethernet) for network integration, RS232/RS485 for industrial connectivity, and USB‑Host for offline data export and firmware upgrades.
✅ Wiegand Input/Output (26‑bit) Expands system flexibility: Wiegand input allows connection of external exit readers (KR500E, KR503) or exit buttons; Wiegand output can feed card data to a central panel in multi‑door configurations.
✅ 50 Time Zones & 5 User Groups Define exactly when each user can access the door. Combine groups with 10 time combinations to enforce department‑specific or shift‑based access schedules.
✅ Anti‑Passback & Fire Alarm Integration Anti‑passback prevents card sharing and tailgating. The dedicated fire alarm input automatically opens the lock for safe evacuation, overriding all other access restrictions.
🔒 Standalone Access Control – Manage Doors Without a Controller
✅ Built‑In Lock Relay (12 V, ≤3 A) Direct connection to electric locks, magnetic locks, or strike locks. No external controller needed – single‑door installations are up and running in minutes.
✅ Wiegand Input for Exit Readers Connect external exit readers (e.g., KR500E, KR503) or hardwired exit buttons. Enables secure two‑way access control with a single SC‑405.
✅ Door Sensor Input Monitors the door position. Reports forced‑open or door‑held‑open events to the log, improving security and maintenance response.
✅ Anti‑Passback (Hard / Soft) Prevents card sharing. Enforces that a user must exit before being allowed to re‑enter, closing a common security loophole.
✅ Fire Alarm Override Fire alarm input automatically releases the lock, allowing barrier‑free evacuation. This overrides any active anti‑passback or time‑zone restrictions, meeting safety codes.
✅ 50 Time Zones & Schedule Bell Assign access schedules by hour, day, or user group. The built‑in schedule bell can be configured to ring during shift changes, breaks, or other timed events.
🏢 Where to Deploy the eSSL SC‑405 Access Control Machine
