Table9.1 Emission related standards
Test description
The electromagnetic wave which
the product emits to the external
*2
space is measured.
The noise level which the product
emits to the power line is
*2
measured.
* 1 : QP: Quasi-Peak value, Mean: Average value
* 2 : Programmable controller is an open type device (a device designed to be housed in other
equipment) and must be installed inside a conductive control panel. The tests were conducted
with the programmable controller installed in a control panel, applying the maximum applicable
input voltage to the power supply module.
Table9.2 Immunity related standards
Test description
An electrostatic discharge is
applied to the enclosure of the
equipment.
An electric field is radiated to the
product.
Burst noise is applied to power
lines and signal lines.
Lightning surge is applied to
*1
power lines and signal lines.
High-frequency noise is applied
*1
to power lines and signal lines.
The product is immersed in the
magnetic field of an induction
*1
coil.
Power voltage is momentarily
interrupted.
* 1 : Programmable controller is an open type device (a device designed to be housed in other
equipment) and must be installed inside a conductive control panel. The tests were conducted
with the programmable controller installed in a control panel, applying the maximum applicable
input voltage to the power supply module.
* 2 : The accuracy of an analog-digital converter module may temporarily vary within ±10%.
