Dear all,
we're implementing 10Base-T1L in our device at the moment. The device is to be installed in a switch cabinet in industrial environment and is powered via 24VDC external power supply.
- Does the 1.5kV isolation requirement for network ports apply to the equipment and if so
- How should one achieve the 1.5kV isolation when implementing PoDL, where power is injected via a differential choke? Shall a 1.5kV isolation DC/DC converter be used for the PoDL supply?
My design below is inspired by the Wuerth SPE physical interface at Single Pair Ethernet | Application Guide | Würth Elektronik (we-online.com)
