Re: Failsafe BNC Connector?

Roelof Bakker

Hello Yannig,

It can be done by using a relay and a NPN or PNP relay driver.
However, when high voltage (spikes) are the cause, a relay will not be fast enough.

Maybe a simpler solution will help: connect a 220 to 470 ohm resistor between the center pin
of the BNC connector and ground. This way you never have a complete open, yet power loss is
