Wiring in a RELCO device.

[Andy Howes]

Can anyone guide me on how to wire up a RELCO device to my two rail layout
please.

I have a RELCO, which when laid on the table has to the left, 2 terminals
plus the words 'OUT' & 'TO TRACK'. On the right are 2 terminals and the
words 'TO CONTROLLER' & '16V IN'. I also have a capacitor.

The track is PECO Setrack and the power supply is by wiring soldered
directly to the 'fishplate'.

Please take me from there ?

Don't use with DCC!

Relco's could originally be wired up two different ways. Later Relcos
should only be wired up one way so I'll describe that :-

The right hand terminals go to a 16v ac supply. The bottom left
terminal goes straight to the controlled dc from the controller and
the top left terminal to the track. The other controlled dc output
from the controller goes direct to the track. The capacitor is fitted
across the controlled dc outputs from the controller. The capacitor
should be a 1 micro farad 50 volt type. IIRC Relco also provided a
capacitor for fitting across the motor brushes of a loco which was a
different value.

Options:- 1)Relco recommended that a 0.5 amp fuse be fitted in the ac
supply.

2) A on-off switch can also be included in the ac supply.

3) A bypass switch can be fitted across the left hand terminals.

4) A DPDT Switch can be used to both bypass and switch off the unit
instead of two separate switches.

5) All leads should be as short as possible to reduce TV interference
With no loco on the track the bulb should light and should go off when
a loco is on a track and only come on intermittently when the loco is
running
