    How have you determined that your relays are at fault??

      Looks like a pretty standard relay. Pin config is the same as in some of the saws I repair. I would take it to a local electrical supply place and see if they can supply it. Does it have specifications for voltages and such on it?

          I would go to an electrical supplier as mentioned and see what they can do. They may be able to identify it with just the part number. Do you have a schematic for this machine? If you could determine what input and output voltage you need you may be able to give them enough info to supply one. As I mentioned the pin format looks pretty standard for commonly used bases.

            You will need to determine your coil voltage.

              relay

              with a ohmmeter, read coil value, if read 1200 ohms, is a 24v relay, but the best is meter volts in relay socket.
