EMI Filter Installation
For low CE-rated radiated emissions, the use of one or two split/snap-on ferrite cores on all
cables or harnesses to/from the device as shown in the drawing on the next page is helpful.
These are also helpful for cables connected to Host USB and Ethernet as well. Use Laird
28A2029-0A2 or similar for inputs/outputs and Power (order Acromag 4001-135), Laird
28A0592-0A2 or similar for USB cable (Acromag 4001-140), and Laird 28A0807592-0A2 or
similar for Ethernet cable (Acromag 4001-139). Locate ferrites by clamping them outside of
all I/O cables or wiring harnesses to/from the module (USB, Ethernet, input/output group,
DC power), and as close to the module as possible. While the use of these ferrites is helpful
to obtain low CE-rated emissions, it may not be required for your application. Note also
that individual cables may share a ferrite, but it is not good practice to combine isolated
circuits inside the same ferrite, but rather separate isolated circuits for safety and greater
noise immunity.
