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 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 Input Module 750-522

2 DO AC 230 V SSR, 3.0 A/ 30 s 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 electronic relay module 750-522 switches a supply voltage up to 230V

AC for connected actuators or AC loads.

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

may be directly connected.

The module is equipped with two TRIACs as switching relays. The semicon-

ductor outputs of the TRIACs allow for the unlimited triggering of the actua-

tors while having no wear on the outputs

The TRIACs are non-floating, i.e. the fieldside voltage supply (35 VAC up to

230 V) 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 DO1 or DO2.

The control of the semiconductor outputs is fully isolated using the internal

system voltage. The outputs are switched at the zero cross.

Description

WAGO-I/O-SYSTEM 750

I/O Modules

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

In addition, a red error-LED for either channel will show if there are any ther-

mal case of overload at the outputs.

In the event of an overload, each output has its own overload protection which

is realized via an internal temperature limit.

In case of an overload, one error bit per channel (bit 0 or bit 1) is set in the in-

put process image. The master control can identify the error with this bit.

The affected output is immediately switched off by the built-in thermal fuse

and the relay will open.

After the output connection has cooled down, the output is triggered again and

the relay will close.

Simultaneously, the error bit is reset in the process image and the error LED

goes off.

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

side.

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 35 V

to 230 V.

The AC 35 V to 230 V supply voltage for the field side, the N (neutral con-

ductor) and the earth (ground) potential is made automatically through the in-

dividual 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

Protective Circuit for Relay Modules".

The output module 750-522 can be used with all couplers/controllers of the

WAGO-I/O-SYSTEM 750.
