* Please prepare contacts with a capacity of 12 VDC and 12 mA or higher.
* If using semiconductor devices, please prepare devices with a leakage current 0.1 mA or lower.
* Caution when using the external control terminal. If connecting an inductive load (relay or coil) to the
output of the external control terminal, insert a diode or use a relay with a surge absorbing element so
that counter-electromotive force is not generated.
