Safety
□
Does the vehicle system have a fail-safe in case of a relay failure? ｐ1/1-1、ｐ1/2-4
□
Has it been confirmed by testing under actual load, actual circuit, and
actual condition? ｐ2/4-1
□
Have load type, load current characteristic, and current value been
checked? ｐ2/4-2～4-9
□
Isn't the applied contact current too small ? (Small current is likely to
decrease the contact reliability.) ｐ2/4-10
□
Has connecting load polarity been checked? ｐ2/4-11
□
Is the load likely to cause instant voltage drop? ｐ2/4-12
□
Isn't the applied contact voltage too high? (High voltage decreases
electrical life.) ｐ3/4-13
□
Isn't applied coil voltage too high? (High voltage affects electrical life.) ｐ3/4-14
□
Isn't short pulse applied to coil? ｐ3/4-15
□
Isn't the switching frequency too high even including at abnormality? ｐ3/4-16
□
Doesn't switching continue for a long time? ｐ3/4-17
□
Does it switch under high temperature? ｐ3/4-18
□
Have precautions been checked for using of coil surge absorption
circuit? ｐ3/4-19
□
Have you checked there is no sneak current or voltage to the relay coil? ｐ3/4-20
□
Is there stray capacitance between lead wires? ｐ3/4-21
□ Have precautions been checked for using of contact protective circuit? ｐ4/4-22
□ Is there a risk of dead short in the power supply? ｐ5/4-23
□ Is there a risk of short circuit in the power supply at load rejection? ｐ5/4-23
□ Is there a risk of insulation and breakdown voltage between contacts in
each pole when high voltage is applied to a twin relay? ｐ5/4-24
□ Has hot start been considered? ｐ5/5-1
□ Is the ambient temperature within the range of use? Also, is the ambient
temperature characteristics considered? ｐ5/5-2
□ Is the applied voltage below the maximum continuous applied voltage? ｐ5/5-3
□ Is there a risk of using PWM control? (PWM control requires careful
attention.) ｐ5/5-3
□ Doesn't coil of twin relay operate at the same time? ｐ6/5-4
□ Hasn't the current continuously applied to coil over a long period? ｐ6/5-5
□ In case of relay operation by electric circuit, is the circuit designed in
consideration of mal-function? ｐ6/6-1、ｐ8/6-2
□ Doesn't the surge voltage of relay cause mal-function or destruction of
transistor circuit? ｐ6/6-1、ｐ8/6-2
□ When relay is applied to an electric circuit, has voltage drop caused by
other electric components on the circuit been considered? ｐ6/6-1、ｐ8/6-2
