TAMS KSM-3

Integrated circuit for operation of the loop turnout

not short-circuit free but shorting precise 

adjustment of the threshold value for the change in polarity by means of a LED 

works in both directions 

Suitable for all digital formats 

Simultaneous operation with multiple trains within the loop 

suitable for use with turntables 

Up to 8 A current for the vehicles in the loop

Principle of operation 

The KSM-3 continuously monitors the track voltage in the terminal loop and detects a short circuit occurring when a locomotive moves out into the terminal loop on or off it. Then the connections are reversed  and thus  the polarity changes in the loop. The operating point is adjusted individually by a trim pot. 

Board dimensions: approx 48 x 52 mm
