Hi Bertie,
I am sorry you are still having this issue, lets see what we can figure out. You mention surviving voltage faults up to 50V which was not mentioned in your original post. These faults are bus faults (A & B) correct? I suspect that due to…
Part Number: SN65HVD1785 Other Parts Discussed in Thread: SN65LBC184 Hi Expert.
My customer request for RS-485 products which have both "Bus fault protection : ±60V" and "Surge current : 6A" .
Does SN65HVD1785 or other products have surge protection…
Part Number: SN65HVD1785 We have developed a system that employs the SN65HVD1785 to interface between several modules. Our modules are powered from a 24VDC source. The 24VDC source can be common(shared) or independently supplied to the modules. Where…
