Wiegand Device Wiring (examples using HID and AWID card readers)
Wiegand Device wiring details are shown below. The +5 VDC power for card readers is from a switched
power supply and is used with Wiegand magnetic stripe readers, etc. It is recommended, when using proximity
card readers, that you should use the +12 VDC power supplied by the board for maximum read distance. The
Access Door Module +12 VDC is a linear power supply (which is required by most proximity card reader
manufacturers).
You should follow the wiring and wire type specifications of the card reader manufacturer that you are using.
Below is the typical wire type and distance specified by most card reader manufacturers; these are the
specifications for the card readers supplied by Delta Controls Inc. Card readers should always be grounded
properly to ensure proper operation (refer to the manufacturers installation data).
