Plug In Module - ADC1614 HGE

The Scientific Solutions ADC1614 HGE 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 BaseBoard / PCI DeskTop unit can accommodate from 1 to 3 ADC1614 HGE modules

The ADC1614 HGE module provides 16 Analog Input channels. Analog signals in the ±10 volt range are digitized by an Analog-to-Digital Converter (ADC). Designed to deliver flexible data, the analog input can be configured for unipolar or bipolar input ranges. A variable gain amplifier at the input to the sample and hold circuit allows the input range to vary. Typical input ranges are 0 to +5v, -5 to +5v, 0 to +10v and -10v to +10v. These input ranges are easily selected by on-board jumpers, and in the case of the 0 to +5v range by using a single 50K precision resistor. You can think of the -10v to +10v and 0 to +10v as the "gain =1" range, and the 0 to +5v and -5v to +5v as the "gain=2" range.

The ADC1614 HGE uses a 14-bit resolution ADC. This means that for the 0 to +5v range, the ADC can measure analog input changes as small as 305uV and for the -10v to +10v range the ADC can measure analog input changes as small as 1.22mv.

The HGE stands for "Hardware Gain External" which is a feature that permits you to change the gain for all the channels to any value by adding a single precision resistor to the module. A special location with two socket pins is provided.

The ADC1614 HGE module requires an Analog Power Supply (APS) Module to also be installed in the BaseBoard. The APS supplies the ADC1614 HGE analog circuits with a regulated low-noise power source. 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).

If you add three ADC1614 HGE modules, then you have 48 Analog Input channels per DeskTop unit. Daisy chain up to four BaseBoard DeskTop units to a single PCI card and you can get 192 Analog Inputs using ADC1614 modules. Add four BaseBoard / PCI cards to a single computer and you have 768 Analog Inputs available!

Configuring the ADC1614 HGE

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. However, the input range of this device is selected by on-board jumpers. Refer to the ADC1614 PGL or PGH for a fully software configured solution.

The control and operation of the ADC1614 HGE module is fully supported by Scientific Solutions device drivers and LabPac function library.

ADC1614 Screw Terminal Option

When you have an ADC1614 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 Analog Input 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.
