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?
