Functional Description

The MGV100 unit is used for reversing the polarity of rail sections.

Mainly commanded by use of LocoIo (MGV50) it is used for turntables or rail loops, to change polarity in a rail section.

The use in rail loops is extremely simple together with the use of MGV50, since MGV50 can directly be programmed to switch

the connected MGV100 when certain feed-backs are activated.
