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 750-455(/xxx-xxx)
4 AI 4-20 mA, Single-Ended 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
2.1.1.3 Description
The analog input module receives signals with standardized values of
4-20 mA.
The module has four input channels. The fieldside signals may be received via
the connections AI 1 and Common (ground) or AI 2, AI 3, AI 4 and Common
(ground). The common (ground) contacts of all four channels have one
common 0 V ground potential.
The input signal of each channel is electrically isolated and will be transmitted
with a resolution of 12 bits.
Broken wire, 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.
The field side supply voltage of 24 V and 0 V for the input module is derived
from adjacent I/O modules or from a supply module.The field supply voltage
is passed on separately galvanically to following modules without own use.
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 analog input module 750-455 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).
