USB DAQ module is low-cost and user-friendly

Paul Boughton

Audon Electronics is launching the DLP-IO20 data acquisition module as a low-cost, easy-to-use data acquisition system for analysing AC voltages, driving 5V relays, controlling and monitoring processes and measuring DC voltages in the range of 0-5V. This module features topside wire terminal blocks for the wiring connections.
The 20 channels on the DLP-IO20 are broken down as follows: three outputs with high-current relay/LED drivers and 17 digital I/O, 14 of which can be set to analogue input mode. In addition, the DLP-IO20 provides two latching relay contacts. Each of the channels and relay contacts can be controlled via simple, multi-byte commands. All operational power is taken from the host PC via the USB port.
Mode of operation for each I/O is automatically changed with each command sent. For example, if an I/O is set to Digital Output-High and then the Digital Input Mode is selected, the I/O is first changed to Input Mode and then the high/low state is read and returned to the host.
