Safety Notes

WAGO-I/O-SYSTEM 750

I/O Modules

1.4 Safety Notes

Warning

Switch off the system prior to working on bus modules!

In the event of deformed contacts, the module in question is to be replaced, as

its functionality can no longer be ensured on a long-term basis.

The components are not resistant against materials having seeping and

insulating properties. Belonging to this group of materials is: e.g. aerosols,

silicones, triglycerides (found in some hand creams).

If it cannot be ruled out that these materials appear in the component

environment, then additional measures are to be taken:

- installation of the components into an appropriate enclosure

- handling of the components only with clean tools and materials.

Attention

Cleaning of soiled contacts may only be done with ethyl alcohol and leather

cloths. Thereby, the ESD information is to be regarded.

Do not use any contact spray. The spray may impair the functioning of the

contact area.

The WAGO-I/O-SYSTEM 750 and its components are an open system. It

must only be assembled in housings, cabinets or in electrical operation

rooms. Access must only be given via a key or tool to authorized qualified

personnel.

The relevant valid and applicable standards and guidelines concerning the

installation of switch boxes are to be observed.

ESD (Electrostatic Discharge)

The modules are equipped with electronic components that may be destroyed

by electrostatic discharge. When handling the modules, ensure that the

environment (persons, workplace and packing) is well grounded. Avoid

touching conductive components, e.g. gold contacts.

1.5 Scope

This manual describes the Digital Input Module 750-424 2 DI DC 24 V,

Intruder Detection of the modular WAGO-I/O-SYSTEM 750.

Handling, assembly and start-up are described in the manual of the Fieldbus

Coupler. Therefore this documentation is valid only in the connection with the

appropriate manual.

2.1.1.2 Description

750-424 is a digital input module with which can receive signals (i.e. window

contacts) from a fixed resistance ratio (R1, R2) in the form of a current.

The module has two input channels which makes it possible to directly

connect two circuits using a 2-conductor technique.

For example, two 2-conductor window contacts on 0 V and signal input DI 1

and signal input DI 2 can be directly wired.

The status of the input channels is indicated via status LEDs. In addition, a red

error-LED will show if there are any shorts or open circuits in either channel.

An optocoupler is used for electrical isolation between the bus and the field

side.

Any configuration of the input modules is possible when designing the

fieldbus node. Grouping of module types is not necessary.

WAGO-I/O-SYSTEM 750

I/O Modules

The field side supply voltage of 24V for the input module is derived from

adjacent I/O modules or from a supply module.The supply voltage for the

field side is made automatically through the individual I/O modules by means

of power jumper contacts.

Warning

The maximum current of the internal power jumper contacts is 10 A. When

configuring the system it is important not to exceed the maximum/sum

current. However, if such a case should occur, another supply module must be

added.

The digital input module 750-424 can be used with all couplers/controllers of

the WAGO-I/O-SYSTEM 750.
