*1 The module is an open type device (a device designed to be housed in other equipment) and must be installed inside a conductive
control panel. Except for the waterproof I/O module, the tests are conducted with the module installed in a control panel. (The I/O
module (waterproof module) is tested outside the control panel.)
*2 The accuracy of an analog-digital converter module may temporarily vary within 10%.
Installation in a control panel
The module is open type devices and must be installed inside a control panel.
This ensures safety as well as effective shielding of programmable controller-generated electromagnetic noise.
■Control panel
• Use a conductive control panel.
• When securing the top or bottom plate using bolts, cover the grounding part on the control panel so that the part will not be
painted.
• To ensure electrical contact between the inner plate and control panel, take measures such as covering the bolts so that
conductivity can be ensured in the largest possible area.
• Ground the control panel with a thick ground cable so that low impedance can be ensured even at high frequencies.
• Holes in the control panel must be 10cm diameter or less. If the holes are larger than 10cm in diameter, radio waves may
leak. In addition, because radio waves leak through a clearance between the control panel and its door, reduce the
clearance as much as possible. The leakage of radio waves can be suppressed by the direct application of an EMI gasket
on the paint surface.
Our tests have been carried out on a control panel having the damping characteristics of 37dB (max.) and 30dB (mean)
(measured by 3m method, 30 to 300MHz).
■Wiring of power cables and ground cables
Near the power supply part, provide a ground point to the control panel. Ground the FG terminal with the thickest and shortest
possible ground cable (30cm or shorter).
