Safety Notes

WAGO-I/O-SYSTEM 750

I/O Modules

1.4 Safety Notes

Attention

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 insu-

lating properties. Belonging to this group of materials is: e.g. aerosols, sili-

cones, triglycerides (found in some hand creams).

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

ronment, 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 envi-

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

conductive components, e.g. gold contacts.

1.5 Scope

This manual describes the Digital Output Module 750-512

2DO 230V AC 2.0 A/ Relay 2NO 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

The connected load is switched via the digital output (relay contacts) from the

control system.

The module has two output channels. Two actuators with ground (earth) wire

may be directly connected to signal output DO 1, N and PE (earth potential) or

signal output DO 2, N and PE.

Each module is equipped with one non-floating make contact relay per chan-

nel, i.e. the fieldside voltage supply (230 V AC or 30 V DC) is connected to

each terminal of the relay and is fed in via the internal power jumper contacts

of an adjacent supply module.

By closing a relay, the field power applied is switched to the second relay con-

nection of signal output DO1 or DO2.

The internal system voltage is used to trigger the relays.

The switching status of the two relays is indicated via green status LEDs.

WAGO-I/O-SYSTEM 750

I/O Modules

Any configuration of the output modules is possible when designing the field-

bus node. Grouping of module types is not necessary.

Attention

An additional supply module must be added for the field supply with AC

230 V / DC 30 V.

The AC 230 V or DC 30 V supply voltage for the field side and the and the 0

V and earth (ground) potential 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 cur-

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

added.

Note

For the protection of relay coils and contacts, inductive loads must be damp-

ened with an effective protection circuit!

Examples of protection circuits can be seen in the section 2.1.2 "Contact Pro-

tective Circuit for Relay Modules".

The output module 750-512 can be used with all couplers/controllers of the

WAGO-I/O-SYSTEM 750.
