17.4.6 Contact Output Wiring
CAUTION
1) Use an auxiliary relay for load-switching if the contact rating is exceeded.
2) Connect a bleeder resistor when a small current is used, so that a current
exceeding 1 mA can be supplied.
3) The output relay has a limited service life. Be sure to connect a CR filter (for AC)
or diode (for DC) to the load.
4) If there is a risk of external lightning surges, use a lightning arrester etc.
5) Since the insulation provided to each relay output terminal is Functional
insulation, provide Reinforced insulation to the external of the device as
necessary. (Refer to the drawing below.)
