17.4.3 Control Output (Relay, Triac, Current, and Voltage Pulse) Wiring
CAUTION
1) The use of inductance (L) loads such as auxiliary relays, motors and solenoid
valves causes malfunction or relay failure; always insert a CR filter for use with
alternating current or a diode for use with direct current, as a spark-removal
surge suppression circuit, into the line in parallel with the load.
2) If there is a risk of external lightning surges, use a lightning arrester etc.
3) The control output should always be used with a load of 10 mA or more.
4) 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.)
