Hello Coves,
We have a medical device employs network port which is intended to be used for communication.
According to IEC 60950, the network circuit in the equipment is called TNV circuit. And the working voltage for TNV-2 or -3 circuit is 120 Vdc.
So, the barrier between TNV circuit and SELV circuits (e.g. RS232, USB port) should be 2 MOOP @120 Vdc, and patient circuit should be 2 MOPP @120Vdc.
Is it too stringent for the separations?
Thanks,
Roland
