Stacked Conditioning

All the conditioning modules in the range are 8 channels and fit on a standard footprint. The main features of the stackable system are as follows:

  • Multiple functions can be stacked together into a maximum 3 card stack
  • Supports Voltage, IEPE (ICP), Dynamic Strain and Bridge Strain simultaneously through physical wiring and software control
  • <3W dissipation maximum per card.
  • 80kHz+ Bandwidth
  • Fully programmable for a variety of functions, integrated into HGL software
  • User changeable for changing requirements.
  • Common power, control and signal interfaces with Dragonfly card.

All stacked systems require a baseboard module which provides all the power supplies and ancillary communications required for the conditioning function cards. This leaves a maximum of two card locations for use with function cards.

The standard stacked configuration for ‘universal’ conditioning includes an AC board with AC Voltage, IEPE, and Dynamic Strain capabilities, and a DC board with DC voltage and Bridge capabilities. The specification off these two card types is provided below.

Stack Module AC Card (IEPE & Dynamic Strain)

Description

An AC signal conditioning Daughter Board for Dragonfly capable of operation with up to 8 off IEPE inputs or up to 8 off Dynamic strain gauge signals using constant current supplies.

The board is designed to stack with the Base Board and if required, a DC signal conditioning Daughter Board.

Specifications

Stack Module DC Card (Bridge Strain)

Description

A DC signal conditioning Daughter Board for Dragonfly. Capable of operation with up to 8 off static strain gauge inputs using constant voltage supplies, or up to 8 off voltage inputs. The card includes internal completion for ½ bridges, and Auto Balance.

The board is designed to stack with the Base Board and if required, an AC signal conditioning Daughter Board.
