The invention provides a power failure emergency manual brake releasing module for an elevator control cabinet. The module comprises a PCB, a power interface binding post, a push-button interface binding post, an air switch interface binding post, a phase sequence detection interface binding post, a voltage reduction resistance interface binding post, a rectification interface binding post and a door lock connection and disconnection detecting interface binding post. The PCB is provided with welding positions connected with the binding posts. The power interface binding post, the push-button interface binding post, the air switch interface binding post, the phase sequence detection interface binding post, the voltage reduction resistance interface binding post, the rectification interface binding post and the door lock connection and disconnection detecting interface binding post are distributed on the PCB, modularization work is achieved in the whole wiring process, the cost is reduced, and meanwhile the assembling efficiency is improved.
