VL-1225/6 Analog Input/Output Board
1-1
Overview
This manual details the installation and operation of VersaLogic’s VL-1225 and VL-1226 analog I/O cards.
The VL-1225 card includes both analog input and output channels. The VL-1226 includes the same analog
input channels, but no output channels. Both cards provide 10- or 11-bit input resolution.
Introduction
In its standard configuration the VL-1225/6 provides 16 single-ended, or 8 differential analog input
channels. It features 10- or 11-bit resolution, 25 µs conversion time, and an on-board DC to DC converter
(re5 volt supply only). The board operates with an input range 0 to +10,
±
5, or
±
10 volts. It can
accommodate input signals in a single-ended, differential, or pseudo-differential configuration.
Each input channel can be read as desired by the system CPU. The board is capable of 25,000 samples
per second throughput.
In addition to the input channels noted above, the VL-1225 card includes two 8-bit analog output channels.
These channels may be jumpered for 0 to +10,
±
5, or
±
10 volt output at 5 mA.
The VL-1225 and VL-1226 are plug-in compatible with the Analog Devices RTI-1225 and RTI-1226 cards.
