This manual is designed to help you use the ACLD-9185. The manual describes how to modify various settings on the ACLD-9185 card to meet your requirements. It is divided into five chapters:

• Chapter 1, "Introduction," gives an overview of the product? features. applications, and specifications.
• Chapter 2, "Installation," describes how to install the ACLD-9185. The layout of ACLD-9185 is shown, the connector pin assignment and power source selection are specified.

The ACLD-9185 is an inexpansive 16-channel SPDT form C relay output board for ISA bus computer in industrial applications. It is fully hardware and software compatible with Advantech's PCLD-785.

The ACLD-9185 provides 16 electromechanical SPDT relay which can be used by any ACL series digital output board with D/O channels on 20-pin flat ribbon connector. You can use 16 on-board relay to control power switches. Each relay is matched with one LED to reflect it's ON/OFF status.

Each relay consumes about 33 mA when energized. When all relays on the board are active , the board takes about 0.53 A from the computer's 12V power bus. Normally the current driving capability of the 12V power source is not good enough . The ACLD-9185 has a jumper switch allowing the user to connect an external +12V power source.


1.1 Features

The ACLD-9185 Relay Actuator and D/I Card provides the following advanced features:

• 16 Single-Pole-Double-Throw relays
• LED indicators to show activated relays
• On-board relay driving circuits
• 120V/1 Amp contact rating
• Simple to program
• Controlled through TTL/CMOS signals or digital output ports of any ACL series board
• Screw terminal for wiring
• Fully compatible with Advantech's PCLD-785

• Industrial ON/OFF control
• External high power relay driving, Signal switching
• Laboratory automation
• Alarm Control
• Lighting Control
• Motor starter control
• Signal control
• Valve/solenoid control

This chapter describes how to install the ACLD-9185. At first, the contents in the package and unpacking information that you should be careful are described. The jumpers setting for the ACLD-9185's base power source selection are also specified.


2.1 What You Have

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

• ACLD-9185 Relay Output Board
• 20-pin 1-meter flat cable assembly
• Nylon standoffs for table-top or panel mounting

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-9185 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-9185.

2.3 Connector Pin Assignments

The relationship between connector pins driver IC's, relay connects, LED's, and resistor arrays on the ACLD-9185 is shown in the following table:

The ACLD-9185's power source can come from internal ( provided by PC bus) or external ( provided by external DC +12V). Both of internal and external source can provide +12V and +5V, respectively. The description of power source is specified as following table:

The desired power source is selected by jumpers :

2.6 Using Relay Output

The ACLD-9185 contains 16 SPDT Form C relays, the connection of Form C realy is shown as the following diagram.

This relay has three contacts : NC ( Normal Close), NO ( Normal Open), and COM( Common). The CM post, located at the middle, can make contact either NO post or NC post. When the control bit is high (1), the COM post and NO post are contacted. If the control bit is low (0), the COM post and NC post make contact.

In normal power-up and reset, the relay is in low status.


2.7 Connection

The ACLD-9185 is digital output daughter board which comes equipped with ACL series multi-function data acquisition cards and digital I/O card. The connection configurations of ACL series cards and the ACLD-9185 are shown as below.
