INZ-TN5A0506-E

•

SG does not have to be connected, but it can be used as an effective countermeasure against
communication errors due to noise.

•

When using the micro controller in an area where the imposed noise level is expected to exceed 500V,
we recommend using a noise filter on the master side as seen in the figure below.
[Noise filter] (Recommended): ZRAC2203-11 (made by TDK Corporation)

RS-485

Noise filter

Master

Main unit

•

If there are problems with EMC during communication, the noise level can be reduced by using a
communication cable with a ferrite core.
Ferrite core (recommended): ZCAT series (made by TDK Corporation)
MSFC series (made by Morimiya Electric Co., Ltd.)
