Power Connections to the Signal Conditioning Card
4-2
4.1 Power Connections to the Signal Conditioning Card
As with the analog inputs, two power options are provided. When the signal
condition board is used with an interface card, power is typically applied
though J9, a 6-pin female socket located beside J7 on the bottom of the board.
For stand alone applications, power can be applied to the three position screw
jack, J6 (see the schematics for details).
4.2 Single- or Dual-Supply Options
Jumpers W10 and W11 are used to define power applied to the signal
conditioning board. W10 and W11 are hard wired based on the installed
op-amps. For the OPA2132 dual supply devices, pins 1-2 are shorted. For the
single supply OPA2350 devices, W10 and W11 are shorted pins 2-3.
Dual supply OPA2132 devices are powered from VA and -VA as shown in
Table 4-1 VA are defined as ±18 V max, but are typically powered from ±12 V
or ±15 V when used with an appropriate interface board.
Single supply OPA2350 devices are powered from 5 VA. All power is
referenced to AGND. Table 4-1 shows the power connector voltages supplied
to the signal conditioning module.

Warning
Do not exceed recommended power supply input voltages to the
5-6K interface board or to the C2000 interface board when used in
conjunction with the DAP signaling conditioning boards.
