4 CH Wiegand to Wiegand converter（4CH wiegand input to 1 CH wiegand output)

Product Description

The 4 Channel wiegand communication converter can be connected to 4 access control RFID card readers or face recognition machines and fingerprint machines at the same time.The Wiegand signals of different devices are concentrated and output to the same Wiegand interface on the access control motherboard can solve the problem of multiple access control devices sharing.The converter uses a high-speed, large-capacity MCU to easily handle 4 Channel signal reception and transmission.

Parameters

• Wiegand Input Interface:4 Channel,it can be connected to card reader or face recognition machine at the same time;
• Wiegand Output Interface: 1 Channel, can be connected to the access controller Board;
• Power supply:+9~24V,30mA;
• Support Wiegand protocol:Default support WG26~WG80,(included WG26/32/34/35/36/37/40/42/44/66/80 And keyboard code input);
• 4 channel input interval: receive 4 Wiegand signals at the same time, no need waiting ;
• The interval between each Channel: not less than 150ms;
• Housing dimension:70*46*20mm;
• Working temperature: -20~60 degrees Celsius;

Interface specification

WG1,WG2,WG3,WG4 is for Wiegand input interface,WG5 is wiegand output interface;

WG1,WG2 and WG3 provide only D0 and D1 terminals,+12V、GND and WG4 are shared;

When wiring, each device should be connected with at least D0 D1 GND 3 wires to ensure that the converter and the card reader or access controller are connected to the same ground.

All the GND of the connected devices should be connected to the converter.

Connected 4 card reader,support WG26~WG80 and keyboard code input，the card information is output in sequence on WG5,in the case of four card readers swiping cards at the same time, the WG1 card number is given priority output,then the WG2 card number, then the WG3 and WG4;When four card readers are connected at the same time, please pay attention to whether the power supply of the access controller board is sufficient. If necessary, external power supply can be used.
