How to Use This Guide

This manual is designed to help you use the ACLD-9182. The manual describes how to modify various settings on the ACLD-9182 card to meet your requirements. It is divided into five chapters:





1. Introduction

The ACLD-9182 opto-isolated D/I board provide 16 opto-isolated digital inputs which can be used by any ACL series digital input board with D/I channels on 20-pin flat ribbon connectors. It is a good solution for preventing floating potential and ground loop problems.

Each input channel has a red LED to reflect it's ON/OFF status . If the input voltage is high , the LED will be lit, otherwise the LED is off. Each input channel is jumper selectable to either AC or DC input, also, the users do not need to care the polarity.


1.1 Features

The ACLD-9182 16 channel opto-isolated D/I board provides the following advanced features:




1.2 Applications :


1.3 Specifications:

Input channels 16
Opto-coupler PC-814
Input current 50 mA max. for DC input
Input voltage 0~24VDC or AC 50 ~1,000 Hz
Logic high > 2.0 V
Input impedence 1.2 K Ohm
Isolation Voltage 1,000V channel-to-channel and channel-to-ground
Input Signal AC or DC, polarity-free( don't care polarity)
Connector 20-Pin Flat Ribbon Cable Connector
Screw Terminal 5mm wiring spacing, 18-22 AWG
Indication Display 16 red LEDs
Size 20.5 cm ( 8.06") x 11.43 cm (4.5")




2. Installation

This chapter describes how to install the ACLD-9182. At first, the contents in the package and unpacking information that you should be careful are described. The jumpers and switches setting for the ACLD-9182's base address and digital input channel configuration (Isolated or Non-isolated) are also specified.


2.1 What You Have

In addition to this User`s Manual, the package includes the following items:

If any of these items is missing or damaged, contact the dealer from whom you purchased the product. Save the shipping materials and carton in case you want to ship or store the product in the future.


2.2 Unpacking

Your ACLD-9182 card contains sensitive electronic components that can be easily damaged by static electricity.

The card should be done on a grounded anti-static mat. The operator should be wearing an anti-static wristband, grounded at the same point as the anti-static mat.

Inspect the card module carton for obvious damage. Shipping and handling may cause damage to your module. Be sure there are no shipping and handing damages on the module before processing.

After opening the card module carton, exact the system module and place it only on a grounded anti-static surface component side up.

Again inspect the module for damage. Press down on all the socketed IC's to make sure that they are properly seated. Do this only with the module place on a firm flat surface.

Note : DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN DAMAGED.

You are now ready to install your ACLD-9182.

2.5 Input Mode Setting

There are 16 jumpers (JP0...JP15) associated with each digital input channel for configuring the channel as AC or DC input. The digital input channels and their corresponding jumpers is shown in the following Table 2.2.

D/I Channel Jumpers D/I Channel Jumpers

Appendix A. Customize the Current Limit Resistor


The ACLD-9182 contains 16 identical opto-isolated control input channels. The circuit diagram of the isolated input channel is shown below. The digital input is first routed through a photo-coupler (PC-814), so that the connection are not polarity sensitive whether used on AC or DC voltage.

In addition, a single-pole filter with a time constant about 5ms is used to filter when the AC inputs passed through.

The normal input voltage range for high state is 3 to 24VAC or DC. The normal input range can be extended by changing the resister (Ri) to limit the current (IF)through the PC-814( opto-isolator to about 10mA . The exact resister value to replace the original resister Ri (1.2K W) can be calculated by the following formulas.
Vin = IF X Ri
Pw = Vin X IF

For example, if the input voltage is 110V, then the Ri should be replace by
Ri = 110 (V) / 0.01 (A) = 11 KW
Pw = 110 (V) X 0.01 (A) = 1.1 W
