PLDS card
A PLDS board is required for each LDT board to be remote supplied. Fuses are positioned on
the PLDS card to select either 40 V or 48 V voltage (48 V as standard unless an S0 interface
supplied with remote power is to be configured on the card).
The remote power is supplied to the LDT card interfaces via the part of the cable terminating with
the J4 connector.
