Hi Kaveh,
We have a few recommendations for Ethernet and RS-232 interfaces.
For Ethernet, there are a few options: ESDS30x (this is either a 2 or 4 channel, unidirectional device with a 3.6 working voltage), ESDS31x (this is also either a 2 or 4 channel…

RS232 and RS485 Protection
Highlights:
RS-485 – Industry standard protocol for data transfer from sensors, etc.
Drive capability of minimum 32 unit loads (UL, 12kΩ)
Uses two signal lines A & B which must be balanced…
Below are the latest recommendations of devices for multiple interfaces that provide you IEC protection and paired with low capacitance that minimizes impact to bandwidth in the system. Please also refer to our System-Level ESD Guide for more details…
