DescriptionThe Single Door Access Control Board 12V Wiegand is a standalone access control system designed for secure and efficient management of a single door. It supports up to 1000 users and can connect to external Wiegand 26–44 RFID readers or DS1990A touch memory readers, providing flexible options for user authentication.This board operates on DC 12V and features a low quiescent current of only 17mA. It includes a relay output that can handle up to 3A for electric locks, ensuring stable performance and compatibility with most 12V access control systems. The controller supports up to two manager cards for administrative functions and offers an adjustable unlock time between 1 and 128 seconds.The communication distance to a Wiegand reader can reach up to 100 meters, while the distance to a touch memory reader is up to 15 meters. Built for durability and wide operating conditions, it can function in temperatures ranging from -35°C to 60°C and up to 90% humidity (ROH compliant). Its compact PCB design makes it easy to integrate into access control enclosures or panels.Technical Specifications:Input Voltage: DC 12V ±20%Quiescent Current: ≤17mAWiegand Format: 26-44 bitsTouch Memory Reader: DS1990AElectric Lock Output Current: ≤3A (Relay Output)User Capacity: 1000 usersUnlock Time: 1-128 seconds (adjustable)Manager Cards: 2Communication Distance (Wiegand Reader): ≤100mCommunication Distance (Touch Memory Reader): ≤15mOperating Temperature: -35°C to 60°CMaximum Humidity: ≤90%, ROHPCB Dimensions: 48 × 32 × 14 mm approx PDF MANUAL
