ZKTeco SRB safety relay for 1 door for stand-alone readers

The ZKTeco SRB is a safety relay for controlling a single door via standalone ZKTeco readers . This compact relay ensures secure and local lock release, significantly reducing the risk of tampering with the access control system.

The SRB is powered by a 12V DC power supply (60 mA) , which is available separately. For a simple and tidy installation, we recommend using a female DC connector – both can be found under the Options tab.

The unit features a Wiegand 26-bit input , making it compatible with various ZKTeco readers. The relay has connections for one electric lock and an output for an exit button (interior push button). This makes it a reliable and secure solution for standalone access control on a single door.

Key Features:
✔ Safety relays for ZKTeco stand-alone systems
✔ Supports 1 door (lock + exit button)
✔ Wiegand 26-bit connection
✔ Secure door unlocking
✔ Power supply: 12V DC / 60 mA (not included)

The ZKTeco SRB enhances the security of standalone readers and prevents direct manipulation of the door lock via the reader. For installation instructions, a datasheet, and software, please refer to the documents below.
