Like the MGV128 switch interface, this unit is made to have a lot of Leds on a switch-board, without many cables.
Each combination of 2 Leds (i.e. red and green) is connected to one output of the GCA50.
Possible uses: * 8 turnout positions each with red and green led. * 8 auxilary function indicators.
Also combination of these two suggestions is possible.
Simply one connector runs to MGV50.
This way of signalling will prove very wire-friendly when a few of them are installes in a switch-board.
Originally set-up as a testboard for new assembled MGV50 units, it proofs to have a much more extended way of use.

|8||Lgn1..Lgn8||Led 3mm green|
|8||Lrd1..Lrd8||Led 3mm red|
* For each groupe of green and red led, a choice can be made to use either red only or green only or both. Other coulour leds are also possible.
* Connector J1 can be replaced by PSS254/10W, This connector lies flat on the circuit board to allow switchboard mounting.
