1: QP: Quasi-peak value, Mean: Average value
2: The programmable controller is an open type device (device installed to
another device) and must be installed in a conductive control panel.
The tests for the corresponding items were performed while the
programmable controller was installed inside the control panel.
Test Item
Measure the emission
released by the product.
Measure the emission
released by the product to
the power line.
Immunity test by applying
static electricity to the
module enclosure.
Immunity test by applying
burst noise to the power line
and signal line.
Immunity test in which a
damped oscillatory wave is
superimposed on the power
line.
Immunity test by applying a
radiated electric field to the
product.
Immunity test by inducting an
electromagnetic field in the
power line signal line.
