BaseBoard ^® Analog Power Supply Module

Scientific Solutions Analog Power Supply Module

The BaseBoard Analog Power Supply (APS) Module provides a low noise power source which is required for modules that perform A/D or D/A fuctions. The APS modules attaches directly to the BaseBoard, occupying one of the module locations. The other three locations can be used by any type of module. One APS module provides enough power from one up to three Analog type modules. With an APS installed, you can have one, two or three Analog type modules or a mix of Analog and Digital modules. The APS module also provides digital I/O functions.

• For use with the BaseBoard / PCI Digital I/O products
• One APS module is required if any Analog type modules are installed.
• For use with the following Analog type modules
  • pn:020042, DAC1612
  • pn:020043, ADC1614HGE
  • pn:020044, ADC1614PGH
  • pn:020045, ADC1614PGL
• Installs inside the BaseBoard PCI DeskTop unit
  • connects to 40 pin header of BaseBoard product
• Provides 24 Digital I/O signals
  • provides a 34 pin header with Digital I/O signals
  • each Digital I/O is paired up with a ground connection
• Compact screw terminals available
• Provides low-noise power supply for other installed analog modules
• Scientific Solutions PowerTag^® compliant
  • LabPac software automatically identifies and configures the module
• Only one module is required per DeskTop unit, and only if the DeskTop unit also contains Analog type of modules as previously listed.

Plug In Module - Analog Power Supply

The Scientific Solutions Analog Power Supply module is an optional module for use with the BaseBoard / PCI digital I/O products. When used with the BaseBoard / PCI product, the module is housed in the DeskTop unit. The purpose of the module is to provide regulated low-noise dual-rail power supplies that are required by other installed modules that perform Analog-to-Digital and /or Digital-to-Analog functions. One APS module provides sufficient power for up to three Analog type modules. A BaseBoard can accommodate from 1 to 4 add-on modules. With one position used for the Analog Power Supply, this leaves three other positions to be used for other moduels. You can add any combination of other modules that you want (Analog Input, Analog Output, Opto-isolated Digital Input or Output, etc).

In addition to providing power for other Analog type modules, the APS also provides Digital I/O signals on a 34 pin header. This allows the APS module to occupy a module location while still providing signal connections.

If you use multiple DeskTop units, each DeskTop unit that contains an Analog type of modules will also require an APS to be insntalled.

Configuring the APS

This module is Scientific Solutions PowerTag compliant, meaning that when this module is attached to a product, such as the BaseBoard / PCI that also has PowerTag technology, the BaseBoard product can query the module and obtain characteristic information, such as the module type, the number of channels, voltage range, etc. This permits auto-configuration of the product without having to prompt the user for this information.

The control and operation of the APS module is fully supported by Scientific Solutions device drivers and LabPac function library.

APS Screw Terminal Option

When you have an APS module installed in the DeskTop Unit, then you will have 34 pin connectors on the front of the DeskTop Unit. You can connect a 34 position screw terminal to the front panel connector(s). The Digital I/O signals are then available to the screw terminals. A 34 position ribbon cable is used to connect between the BaseBoard unit and the screw terminal unit. Typically, the striped edge of the ribbon cable connects to Pin 1 of the connectors.
