General information

DIO2908A SIL Technical Manual ver. 1.00 4

1. General information

This is the SIL Technical Manual for the EKE-Trainnet® DIO2908A Digital Input Output

H module.

This manual is for system user and for designers.

This manual contains following chapters:

Chapter 1: General information

Chapter 2: DIO module features and operation

Chapter 3: Installation

Chapter 4: Technical data

This manual does not include information on other EKE-Trainnet®

products than the DIO SIL module. If you need information about

other EKE-Trainnet® products (e.g. modules, racks or accessories),

refer to the manual of the product in question.

This chapter includes general information about this manual. The following topics are

covered in this chapter:

Symbols used in this manual

Safety considerations

Correct handling of the module

Disposal of the module

General information

Symbols used in this manual1.1

In this manual, situations that require caution are marked with special warning symbols.

The warning symbols appear in the beginning of the appropriate chapter. The following

symbols are used.

Figure 1.1 Electric shock warning symbol

Figure 1.2 ESD warning symbol

Figure 1.3 General caution symbol

Figure 1.4 Note symbol

Figure 1.5 Separate collection for Waste Electrical and Electronic Equipment according to

Directive 2002/96/EC (WEEE)

Safety considerations1.2

It is not allowed to remove the DIO module from system / rack. It

is also not allowed to update the module software or to perform

module level diagnostics or repairs.

1.2.1Considerations in safety system design

It is not possible to detect all possible module internal errors. It is recommended to use

the following design guidelines:

The safe-state design approach and output readback should be implemented on

application level.

To increase availability the system level redundancy should be implemented.

In case there is communication error on the module level the module safe state

will be activated (refer to chapter 2.5.5 on p.18).

Correct handling of the module1.3

Electrostatic discharge (ESD) can damage electronic circuits. EKE products are

protected against ESD. However, you run the risk of delivering electrostatic discharges

to the module whenever you handle it or any of its components.

To avoid this risk, only handle the DIO module at a static-free workstation. If this is not

possible, you must ground yourself using a wrist strap and a resistive connection cord.

Remember to handle the module according to these instructions even when you are

removing a defective module and sending it to maintenance.

Disposal of the module1.4

In order to reduce the environmental load over the product’s entire lifecycle,

EKE-Electronics’ products are designed to be as safe as possible to manufacture, use,

and dispose of

Parts which can be recycled should always be taken to the appropriate processing

centres, after hazardous waste has been removed. All parts and components containing

hazardous materials must be disposed of in accordance with waste legislation and

instructions issued by the environmental authorities. The risks involved and the

necessary precautions must be taken into account when handling waste products.

Therefore, please execute proper processing of disposal in accordance with local law.

Module identification2.1

The following figure shows where to find the version and the modification

information.

DIO module features and operation

9DIO2908A SIL Technical Manual ver. 1.00

Figure 2.1 The location of version and modification information

A modification label shows the module modification. It is located on the back

connector. The label includes letters, and the modification is indicated by crossing

out one. If letter A is crossed out, the modification is A, and so on. This modification

field is for the entire module.

The circuit board may have a different modification level, indicated by numbers,

which are printed on the board’s modification field. This is found on the back side of

the circuit board on the lower left section.

DIO module features and operation

DIO2908A SIL Technical Manual ver. 1.0010

The Board test label indicates that the module has gone through the required testing

cycle. It is located above the board modification field.

The Board serial number identifies the module. It is located above the board test

label.

The Board ID above the Board serial number indicates an ID for the circuit board.

The Module ID located just below the front connector indicates an ID for this entire

module.

DIO module features2.2

The DIO module has 32 channels. From all the channels 24 are inputs and eight (8)

may function as either input or output .The Input and Input/Output channels are

divided into two groups that can have different Group Voltages (e.g. 110 V and 24

V). The two groups are not galvanically isolated.

The following figure presents a general functionality diagram of the DIO module.
