Relays chosen should be suitable for the proper coil voltage as well as appropriate current carrying capability. A relay capable of 5 to 10 amps DC is adequate. The diode in series with Relay K1 is any general purpose 1 amp style such as the 1N400x series. If the motor rotates incorrectly, simply reverse the leads to the motor or from the External DC Supply.
The controller also has the capability to, with a small modification, allow you to input your external DC voltage into the unit and use the internal relays to control the rotator as usual.
This information is presented as a guide to help the user realize a solution to the long cable run situation.
