S88-feedback module-2S

This standard feedback decoder has 16 inputs which are connected to ground.
It has a temporal extension of 2 seconds.
Short pulses will thus reliably detected.
Reed contacts or switches can bounch.
This means that they switch several times per second
This can lead to incorrect counting.
With the 2 second extension is only one pulse is counted.

This may be:

• The axes by a train
• Reed switches that are triggered magnetically
• Switches which are operated by hand
• Relay contacts of circuits
• Electronics, such as traffic light decoders, which switch to minus.
