ACL-8112HG - Enhanced Multi-Function Data Acquisition Card

ACL-8112HG
Enhanced Multi-Function Data Acquisition Card

Introduction

The ACL-8112 Series is the next generation of the ACL-812PG card. The register structure of this series is fully compatible with the ACL-812PG, so all of the software for ACL-812PG will run with the ACL-8112 Series.

The ACL-8112 Series consists of two products, the ACL-8112HG and ACL-8112DG. The ACL-8112HG provides special high-gain programmable instrument amplifier for low level input applications, such as measure thermocouple signals. The ACL-8112DG provides high speed sample rate (up to 90KHz) at all gains (x1, x2, x4 and x8).

The ACL-8112 Series features 16 single-ended or 8 differential analog inputs at up to 90KHz, 2 channels multiplying 12-bit double-buffered analog output, 16 digital inputs, 16 digital outputs and one timer/counter channel.

To reduce RFI and EMI noise and assure accuracy on sensitive analog inputs, analog circuitry is powered from an on board DC-to-DC converter that provides high noise isolation from the PC's power.

Software Specifications

All the software which can be run on the ACL-812PG and Advantech's PCL-812PG can also be run on the ACL-8112 Series. This means the ACL-8112 Series is 100% register compatible with the 812PG cards.
Completely compatible with other data acquisition software such as LabTech's Notebook, DasyTech's DasyLAB, NT's LabVIEW and LabWindows, Advantech's Genie, etc.
For the users who are writing their own programs, the ACL-8112 Series are supported by a comprehensive set of drivers and programming tools. Software support is provided for Utility, C/C++ Program Library, Windows DLL Driver and Data Acquisition Software Kit (ACLS-DASK).
