Hello all,
I am involved in a project to restore the Pennsylvania Railroad Power
Director's office in Harrisburg, PA to simulated operation.
https://www.harrisburgnrhs.org/pdo
The supervisory control units use modified 215 relays for the line
circuits. As some of the relays were fried, we replaced the "guts" with
solid state relays and found them to be very reliable. As the SCADA
units are temperamental enough by themselves, we found that the solid
state relays provide one less "unknown" when restoring them to life.
Since we don't want to destroy the remaining 215 relays, we are looking
for damaged or burnt out 215 or 255 relays which we use to house the
solid state components. Does anyone have any that they are willing to
contribute to the project?
Thanks,
Paul Wills
