easily. Remove the crimp terminal and polish the ends before
attempting to solder them.

of internal relays when driving a large capacity load. This is
particularly important when the output relay is switched frequently
(e.g., with proportional control).
supply voltage of the power supply may vary greatly when the load
is open or closed if the capacity of the power supply is not large
enough. Make sure that the capacity of the power supply is large
enough so that the supply voltage range will be always from 90% to
110% of the rated supply voltage.
