Standalone RFID Access Controller

The YINGHUA BC40 operates as a self-contained door lock that reads 125 KHz cards and accepts keypad codes without any computer connection. It stores up to 8000 user credentials and supports card-only, code-only or combined entry modes for flexible access control.

Capacity and Environmental Limits

The unit holds 8000 cards and passwords, which suits small to medium offices or residential blocks, but larger sites will exceed its memory. It functions reliably from -20 to 70 Celsius in humidity up to 95 percent, so extreme cold or condensation beyond those ranges will stop it working.

12 V DC Power Requirement

This lock runs on a 12 V DC supply and drives its relay at 12 V DC 2 A, so an installer must provide a matching power source; the device cannot operate on mains voltage or battery power alone.

Questions about this item

Will the BC40 work with my existing WG26 or WG34 controller?

Yes, the BC40 has WG26/34 input and output so it can connect directly to controllers using those protocols.

How do I confirm the BC40 is operating correctly after installation?

The backlit metal keypad lights up, the doorbell button responds, and the relay clicks when a valid card or code is entered.

Does the BC40 include the 12 V power supply and exit button?

The package contains the BC40 reader and mounting hardware; a DC12 V supply and separate exit button must be purchased separately.
