Introduction
The PCL-818L is a high performance multi-function data acquisition
card for IBM PC/XT/AT or compatible computers. It offers the five
most desired measurement and control functions: 12-bit A/D conver-
sion, D/A conversion, digital input, digital output and timer/counter.
Automatic channel scanning circuitry and on-board SRAM let you
perform multiple-channel A/D conversion with DMA and individual
channel gains.
The PCL-818L is an advanced new version of our popular PCL-818.
A custom 160-pin ASIC chip integrates the functions of the full-size
PCL-818. This chip gives you maximum accuracy and reliability,
along with minimum cost, size and power consumption.
The resulting half-size card is fully software compatible with the PCL-
818. This puts rich software support and a wide variety of external
signal conditioning boards at your disposal.
The PCL-818L is excellent for data acquisition, process control,
automatic testing and factory automation.
