AIM104-OUT16 Technical Manual Introduction

Introduction

The AIM104-OUT16 is an 8-bit PC/104 module providing 16 opto-isolated Darlington

driver outputs. The module provides electrical isolation of up to 1500V between your

PC/104 based control system and the electrical system you are controlling. The

isolation between adjacent channels is limited to 100V by the wiring and connectors.

The outputs are configured as current sinking drivers with a drive capability of up to

600mA for channels 0 to 4, and up to 300mA for channels 5 to 15.

Features

• Maximum operating voltage for the load is 30V.

• Maximum switching frequency for each output is 40KHz.

• Switching time delays: OFF to ON 5ms and ON to OFF 8μs.

• All outputs include a catch diode to the positive supply for added protection when

driving inductive loads.

• Module access LED (on all decoded addresses).

• 8-bit PC/104 (IEEE996) bus interface.

• Operating temperature range: -20°C to +70°C.

• Power consumption from the PC/104 host, max 125mA at +5V.

• MTBF: 702,000 hours (using generic figures from MIL-HDBK-217F at ground

benign).

AIM104-OUT16 Technical Manual Introduction

Handling your board safely

Anti-static handling

This board contains CMOS devices. These could be damaged in the event of static

electricity being discharged through them. Observe anti-static precautions at all times

when handling circuit boards. This includes storing boards in appropriate anti-static

packaging and wearing a wrist strap when handling them.

Electromagnetic compatibility (EMC)

The AIM104-OUT16 is classified as a ‘component’ with regard to the European

Community EMC regulations and it is the user’s responsibility to ensure that systems

using the board are compliant with the appropriate EMC standards.

The opto-isolation provides a good barrier for noise emissions generated by the high

frequency host PC/104 system. The AIM104-OUT16 includes additional filter

components on-board to minim

ise the emissions of high frequency noise. Because of

this, the earth tab supplied with the module must be connected to the chassis of the

system by a good earth wire.

If the electronic system requires input protection against high voltage transients (to

meet CE requirements), it is recommended that an external interface board is located

at the point where the external wiring enters the electronic system enclosure:

Packaging

Should a board need to be returned to Eurotech Ltd, please ensure that it is

adequately packed, preferably in the original packing material.

RoHS compliance

The European RoHS Directive (Restriction on the Use of Certain Hazardous

Substances – Directive 2002/95/EC) limits the amount of six specific substances within

the composition of the product. The AIM104-OUT16 is available as an RoHS-6

compliant option and is identified by an -R6 suffix in the product order code. A full

RoHS Compliance Materials Declaration Form is included in

Appendix B – RoHS-6

Compliance - Materials Declaration Form

, page 14. Further information about RoHS

compliance is available on the Eurotech Ltd web site:

What items are provided?

The AIM104-OUT16 is supplied with the following items:

• The AIM104-OUT16 or AIM104-OUT16-DC/DC board.

• Mounting kit.

Getting started

Unpacking and connecting up

To begin using the AIM104-OUT16 board, follow these steps:

1 Power down your computer.

2 Install the board in a spare PCI slot.

3 Power up your computer and install the appropriate driver available from our

website:

34H5Hwww.eurotech-ltd.co.uk/en/downloads.

AIM104-OUT16 Technical Manual Operation

Operation

Switch ON each output channel by writing a 0 to the channel control register. The

Darlington output sinks current when switched ON. On power-up, or when reset is

asserted, all the outputs are disabled and switched OFF. If the power on the PC/104

host system is switched off at any time, all outputs are switched OFF. You can enable

the outputs by writing to Base +2 address. The following diagram illustrates this:

AIM104-OUT16 Technical Manual Power dissipation and current handling for devices IC1 and IC2

Power dissipation and current handling for devices IC1 and

IC2

In order to prevent damage to the output Darlington drivers, the total power dissipation

per device must be below 1.56W at 25°C. This must be de-rated at 12.5mW/°C above

25°C. Power dissipation for each channel is calculated as load current times 1.5.

• Channels 0, 1, 2, 5 together<1.56W.

• Channels 3, 4, 6, 7, 8 together<1.56W.

• Channels 9 – 15 together<1.56W.

The following chart provides guidelines for the maximum current handling for each

device, and how the handling is de-rated with increased temperature:

Output channels 0 to 4 are capable of sinking up to 500mA. All of the other

channels can sink up to 300mA.

For further information about the output drive capability of this product, please refer to

The board access LED gives a momentary flash when the board is successfully

accessed. The module registers are accessed at the following locations:

Address Read/write Register name Bit functions

Base Write Channel control 0-7 Bit 0-7: 0 = ON 1 = OFF

Base Read Channel status 0-7 Control register O/P (valid only when

bit 0 of output enable control = 1)

Base+1 Write Channel control 8-15 Bit 0-7: 0 = ON 1 = OFF

Base+1 Read Channel status 8-15 Control register O/P (valid only when

bit 1 of output enable control = 1)

Base+2 Write Output enable control Bit 0: Channels 0-7

Bit 1: Channels 8-15

0 = OFF 1 = Enabled

Bit 2-7: Not used

Base+2 Read Not used

Base+3 Write Not used

Base+3 Read Not used

We recommend that, during system initialisation, the values to be output

are written to the control registers prior to enabling the output channels.

The output connector includes 4 isolated ground connections. If you intend

to use the module to drive many loads, it is recommended that as many as

possible of these are connected to the ground of the external power supply.

Remember that the maximum current rating of typical ribbon cable is 1A.

You can help to reduce electrical noise generation by distributing the load

current on the ground return path amongst a number of ribbon cable wires.
