15. NW6410 WaveNet Buscoupler
15.1 General
There must always be 1 buscoupler (BC) within any DAQ to provide
data communications to the Core Module. There cannot be more
than a single Buscoupler on a single DIN busbar. 24V AUX output,
resettable fuse at 750 mA, 24V AUX input, max 1A.
15.2 Location and mounting
The NW6410 WaveNet Buscoupler connects to the DIN busbar by
mounting it from the top first and only in a vertical direction. Once
the adaptor is attached to the DIN rail it should not be shifted in a
horizontal direction (!) since this will render the feathering contacts
between the module and the DIN useless and the system will fail
beyond repair.
15.3 Power supply
This unit has 1 x 1000 TX PoE port, receiving 802.3af compliant PoE @48V and fully relies on the
Ethernet PoE supplied from the Core Module. The total power budget is 12 Watts.
15.4 DAQ Card Power Budget
The typical power budget required by the DAQ cards are as follows…
For example:
1 x Bus Coupler (3W) – always required for each DAQ system.
1 x 16 NMEA (2.78W)
1 x 24 DIN (3.4W)
Requires 9.18W which is within the 12W budget.
