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.

2.1.2.3 Description

The 750-461 analog input module and its 750-461/xxx-xxx variations allow

Pt or Ni Resistive Temperature Devices, RTDs, to be measured in the field.

It can also be used to measure resistances in the field.

Depending on the operating mode, the resistance value is converted to a

temperature or directly sent out by the module. A microprocessor within the

module is used for converting and linearizing the measured resistance value

into a numeric value proportional to the temperature of the selected resistance

sensor.

The operating mode of the 750-461/003-000 variation can be set by using the

WAGO-I/O-CHECK 2 start-up and diagnostic tool (Item No.: 759-302). The

default setting is Pt 100. After setting the parameters, the module behaves like

the version with the selected operating mode.

The operating mode of the 750-461 basic module described in this manual is

for a Pt 100 resistance sensor.

The analog input module is a 2- to 3-conductor device and has 2 input

channels. Two devices may be directly connected to the module.

For example, two 3-wire sensors can be connected either to +R1, RL1 and –

R1 or to +R2, RL2 and –R2.

For the connection of 2-wire sensors, putting of a bridge is necessary between

+R1 and RL1 or +R2 and RL2.

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

connection is made automatically when snapped onto the DIN rail.

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

side.

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

the channels are indicated via a green function LED. A broken wire, short-

circuit or overrange are indicated by a red error LED per channel.

Display Elements

WAGO-I/O-SYSTEM 750

I/O Modules

After the error has been corrected, the module needs up to 4 seconds to output

a correct measured value, the module 750-461/000-006 needs up to 12

seconds.

Any configuration of the input modules is possible when designing the

fieldbus node. Grouping of module types is not necessary.

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 750-461 and its variations 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).
