Oscillatory surge voltage
If a vibration damping waveform (1～1.5MHz, Peak voltage : 2.5～3kV) is repeated and added,
there is no malfunction.
Auxiliary supply circuit (Normal / Common)
AC input circuit (Normal / Common)
Contact output circuit (Common)
Square wave impulse noise
If a noise (1μs, 100ns width) is repeated and added, there is no malfunction.
Auxiliary supply circuit (Normal / Common) Over 1.5kV
AC input circuit (Normal / Common) Over 1.5kV
Contact output circuit (Common) Over 1.0kV
Electric wave noise
If intermittence irradiation of the electric wave of a 150,400MHz band is done by (1W, 1m),
there is no malfunction.
Electrostatic noise
±8kV (at the case of energization) is that there is no malfunction.
±10kV (at the case of no-voltage) should not have damage or the abnormalities of parts.
