Auxiliary Relay
▪ If the wattage of the load is greater than the rating of output relay, an auxiliary relay should be
used to on/off power on the load.
▶ When an inductive switch as a relay and a solenoid valve is used, it may be a noise source. A
protective circuit should be installed to suppress a surge. CR filter (AC) or Diode (DC) should be
connected with the mechanical contact in parallel.
▶ CR FILTER recommended
