Other Parts Discussed in Thread: THVD1400,
Dear Experts,
I want to ask about protection of RS485 devices. We will have two RS485 communication, one for the internal bus among cards and second one for communnication with external world which may be a high voltage outdoor auto-recloser in the 33KV gantry.
In the datasheet of the device "THVD1400" it recommended adding TVS (or MOV for higher voltages) while the datasheet of "ISOW1412" didn't recommend the same.
So, my question is: Do we need to add TVS or MOV for the "ISOW1412" which will be used for communication with outdoor devices?
Regards,
Mohammad.
