Manual (rev A5) says 28V 150mA max (page 43).

Hi Ok,   it does mention up to 30v but no current is specified. I guess it should handle 250m ma then.
Thanks

I do not have the KX2 manual in front of me.  But I do recall the KX2 manual specification does list a maximum voltage. (I think is was in the range of 40 vdc.) I will look it up at reply back.  The manual does not list a maximum current.  However, my KX2 does handle the 12v relay in my Ameritron 500m. That I use in my travel trailer.
