WAGO-I/O-SYSTEM 750 XTR
750-457/040-000 4AI +/-10V DC S.E. /XTR

Device Description

3
The Analog Input Module 750-457/040-000 (4AI +/-10V DC S.E. /XTR) processes
analog signals with the norm value of ±10 VDC.
The module has 4 input channels. The signals of the field side may be received
via the CAGE CLAMP
and common (ground) each.
The common (ground) contacts of all 4 channels have 1 common 0 V ground
potential.
Common 0 V ground potential
This potential is not the 0 V field power of the blade contacts!
The input signal is electrically isolated and is transmitted with a resolution of
12 bits.
The assignment of the connections is described in the "Connectors" section.
Connection examples are shown in section "Connect Devices" > ... >
"Connection Example(s)".
One red error LED per channel indicates when the measuring range is exceeded
or falls below for the respective channel.
The meaning of the LEDs is described in the "Display Elements" section.
With consideration of the power jumper contacts, the individual modules can be
arranged in any combination when configuring the fieldbus node.
An arrangement in groups within the group of potentials is not necessary.
Power to the internal electronics is supplied via internal data bus.
The I/O module receives the 24 V voltage supply and the 0 V potential for the
field level from an upstream I/O module or from the fieldbus coupler/controller via
the power jumper contacts used as blade contacts. These potentials are passed
through without being used galvanically isolated to subsequent I/O modules.
Do not exceed maximum values via power contacts!
The maximum current that can flow through the power jumper contacts is 10 A.
The power jumper contacts can be damaged and the permissible operating
temperature can be exceeded by higher current values.
When configuring the system, do not exceed the permissible maximum current
value. If there is a higher power requirement, you must use an additional supply
module to provide the field voltage.
