PRCCB Relay transformation on GZ Metro APM Line

The old car used Plug-in installation. Because of the shaking brought by vehical running,the relay often fall off from the bracket , which leads to signal lost.


After analysing and evaluating on the spot, we fully reuse the old relay.

We design one more PCB board,and weld the relay on it. The old relay body and protection circuit are retained. Also we do not change the original mounting position.

Throughly solve the relay falling-off situation. And this mode of relay installation obtain a good expansibility.
