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 750-408

4 DI DC 24 V 3.0 ms, Low-Side Switching 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.

Description

WAGO-I/O-SYSTEM 750

I/O Modules

2.1.1.2 Description

The digital input module 750-408 receives control signals from digital field

devices (sensors, switches, etc.).

The module is a 2- to 3-conductor device and has 4 input channels. Two

sensors may be directly connected to the module.

As an example, two 3-conductor sensors can be directly connected using

connection 24V, 0V and signal input DI1 or DI2. The connection of more

sensors to signal inputs DI3 and DI4 requires a field side connection module

(750-614) for 24V and for 0V, if need be.

The module is low-side switching, which means that the status of the input

channels is "high" if the input channels switch to 0V.

Each input module has an RC noise rejection filter with a time constant of

3.0 ms.

The status of the input channels is indicated via status LEDs.

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.

The field side supply voltage of 24 V 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 750-408 can be used with all couplers/controllers of

the WAGO-I/O-SYSTEM 750.
