Relay wiring

MiguelitoOGR Forum Member

I'm hoping that someone can explain as simply as possible for one not too well grounded (excuse the pun) in electronics how to hook up a set of MTH crossing gates to a relay switch and an insulated outside rail for operation. There are four color coded wires from each gate - red, black , yellow, and white (also a blue which I don't believe is employed). The relay switch I have is labeled: SRE 202D, 12VDC, 5A 240 VAC, 5A 28 VDC and has 7 pins. I have visited other discussions on this topic here but they leave me baffled. Any help would be appreciated. Thanks for reading. Mike
