External voltage supply
For the EMF2179IB communication module, always use an external voltage supply.
The external voltage supply of the communication module is provided via plug contacts V+
and V−.
Designation Description
V+ The external supply exceeds the selection of the DeviceNet specification.
U = 24 V DC (21.6 V − 0 % ... 26.4 V + 0 %)
I = 100 mA
V− Reference potential for the external voltage supply
If the distance between the DeviceNet nodes is larger than normal, you can use several
voltage supplies.
Drive controller External voltage supply
820X Always required
821X, 822X, 824X
93XX
ECSxS/P/M/A The external voltage supply is necessary if communication is not to be
interrupted when the standard device supply fails.
