How to Use This Guide
This manual is designed to help you use the ACL-7225. It describes how
to operate the ACL-7225 card to meet your application requirements. It
is divided into three chapters:
lChapter 1, "Introduction," gives an overview of the product features,
applications, and specifications.
lChapter 2, "Installation," describes how to install the ACL-7225. The
layout of ACL-7225 is shown, the DIP switch setting for base
address, and jumpers setting for input configuration are specified.
lChapter 3, "Registers Format," describes the registers format and
how to program the digital input and output channels on the ACL-
7225.

Introduction
The ACL-7225 -16-CH Relay Actuator and Isolated D/I card is a
compact size ISA Bus card for industrial applications.
This card provides 16 relay actuators and 16 opto-isolated digital input
channels. You can use 16 on-board relays to control power switches or
ON/OFF control devices. Each relay is matched with one red LED to
reflect its ON/OFF status.
The 16 opto-isolated D/I channels are used to collect digital input data.
It is very essential to use isolated input to prevent the ground loop
problems. Each input channel is jumper selectable to either AC or DC
input control voltage. The isolation voltage is guaranteed at 1,000V, so
that common-mode voltages and voltage spikes that often occurs in
industrial environments are safety isolated form the PC and the ACL-
7225.
The digital I/O is via two 37 pin D-type connectors that project through
the computer case at the rear of the board.
1.1 Features
