HO UK model rail
The m83 when directed by the mobile station hand controller sends a brief pulse to effect the switch. Continued pressing of the controllers button, does not lead to an extended pulse. The pulse settings can be updated from the mobile station controller
The m83 decoder derives it electrical power by:
M83 maximum current load = 3 amps
The m83 decoder is capable of replacing four 74461 under the track decoders, and at current prices of approx 30 Euros for the m83 and approx 20 Euros for just one under the carpet decoder that makes using the m83 considerable saving.
Effectively each point motor 74461 is wired back to the m83 with three wires – a common and two others for either straight through or to the turning.
