Reverse loop module and variants

Electronic module for rever loops
The connection is very simple.
The electronics detects short-circuiting short-circuits in reverse loops and poles so quickly that neither the decoder nor the control center notice it.
No mechanical components available
Depending on the model for 1 or 3 reverse loops.
