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 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 750-523

1 DO AC 230 V 16 A/Relay 1a/Pot. free 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

A connected actuator or load is switched via the relay output module.

The 24 V supply is derived from the power jumper contacts to trigger the re-

lays.

The module has one output channel and enables the connection of one or two

actuators.

The signal output DO has two parallel connections so that an actuator can be

wired using one or two conductors of cross section > 2.5 mm². It is also possi-

ble to connect two actuators in parallel.

The module is equipped with an isolated contact relay so that only the connec-

tion points of the relay contacts are available on the fieldside.

Due to the isolated contacts, it is possible, for example, to connect several re-

lays in series by grouping these modules.

Description

WAGO-I/O-SYSTEM 750

I/O Modules

The relay contact L can be supplied with 230 VAC external voltage.

By closing the relay, the voltage applied to L will be switched to the second

relay contact DO.

The relay contact L is also equipped with two parallel connections.

Therefore, the voltage can be applied via one or two conductors of cross sec-

tion > 2.5 mm². The voltage can also be supplied to the following modules via

the second connection.

The automatic or manual operating mode can be selected using the "man-

ual/automatic" switch.

In the "automatic" operating mode, the relay is operated via the control system

requiring a 24 V power supply fed in via the internal power jumper contacts of

an adjacent supply module.

In this operating mode, manual status transitions which may occur via the red

"manual operation" switch (1/0) will be reset by the control system after less

than 500 ms.

In the "manual" operating mode, the relay cannot be switched via the control

system. Operation can only be performed manually via the red "manual opera-

tion" switch (1/0). Moreover, the actuator can be switched without 24 V

power supply.

Description

WAGO-I/O-SYSTEM 750

I/O Modules

Note

The relay is bistable, i.e. stable in both defined switched status. Therefore, the

current switched status and information about this status remain unchanged in

the event of a loss of voltage.

The relay meets both international standards of IEC and DIN EN 61810 part 1

/ VDE 0435 part 201 as well as overload and short circuit requirements of IEC

and EN 61036 / 61037.

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

bus node. Grouping of module types is not necessary.

Attention

The relay output module 750-523 should not be directly connected to the

following modules: analog input module 750-467 (2 DI DC 0-10 V, up to

version number 3005), 750-468 (4 DI DC 0-10 V, up to version number 3005)

and 750-476 (2 DI DC +/-10 V, up to version number 3005)!

The output module has 24 V and 0 V built-in power jumper contacts. The

24 V power supply is used to trigger the relays.

The module is powered using an adjacent I/O module or a supply module via

power jumper contacts. The power supply to the following I/O modules is

made automatically by means of power 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.

Attention

A power supply module is required to connect the following I/O modules to

the ground!

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 750-523 can be used with all couplers/controllers of the

WAGO-I/O-SYSTEM 750.
