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 Analog Input Module 750-479

2 AI DC ±10 V, Differential Measurement Input 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

This analog input module receives signals with standardized values of ±10 V.

The module has two differential input channels and can receive differential

signals via the connections +AI 1 and -AI 1 or +AI 2 and -AI 2.

The Shield (screen) is directly connected to the DIN rail. A capacitive

connection is made automatically when snapped onto the DIN rail.

The input signal of each channel is electrically isolated and will be transmitted

with a resolution of 14 bits(13 bits + sign bit).

The operational readiness and trouble-free internal data bus communication of

the channels are indicated via a green Function LED. Overrange or underflow

of the measuring range is indicated via a red error LED.

Any configuration of the input modules is possible when designing the

fieldbus node. Grouping of module types is not necessary.

The voltage supply is done via system voltage.

Attention

This module has no power contacts. For field supply to downstream I/O

modules, a supply module will be needed.

The analog input module 750-479 can be used with all couplers/controllers of

the WAGO-I/O-SYSTEM 750 (except for the economy types 750-320, -323,

-324 and -327).
