5.3 BPL010-502/503 backplane with opto-isolator card

These backplanes are provided with an additional plug in card which provides opto-isolation for many of the NextMove ES signals.

On BPL010-502, the general purpose digital outputs are PNP (current sourcing) outputs. The general purpose digital inputs are activated when a positive voltage is applied.

On BPL010-503, the general purpose digital outputs are NPN (current sinking) outputs. The general purpose digital inputs are activated when grounded.

There are two 96-pin connectors present on the opto-isolating backplane. The male connector accepts the opto-isolator card. The female 96-pin connector nearest the edge of the backplane accepts the NextMove ES card. The backplane will not operate without the opto-isolating card.

In the following sections, the signals AGND, DGND and Shield are listed with nominal corresponding pins on the 96-pin connector, although they are all electrically connected on the backplane. The OUT COM pin on connector X11 is not connected to ground.

All terminals labeled USR GND are electrically connected on the backplane, but are not connected to the AGND, DGND or Shield terminals. USR GND forms an independent common connection for the 0V side of the external power supply used for the digital inputs and outputs. It will be necessary to link the OUT COM or USR COM terminal to USR GND to allow the digital outputs to operate. However, the OUT COM and USR COM connectors have different purposes depending on model - see sections 5.3.6.1 and 5.3.6.2.

Some signals are duplicated on multiple identically named pins on the 96-pin connector. In these cases, only the lowest numbered pin is listed.

CAUTION: Some components are static sensitive devices. Take appropriate ESD precautions when handling the backplane.
