(*Note)
As SOL
I
and SOL
II
are SSR outputs, they output
100VAC even in the waiting (or standby) state. Minimum
load current of the circuit is 10mA. If the product is used
below the minimum load current value, the remnant
voltage may cause malfunctions. In case of using in such
condition, connect a dummy resistor in parallel with the
load and keep the total circuit current (that flows load and
dummy resistor) at 20 mA to 1 A.
