WAGO-I/O-SYSTEM 750 XTR
750-453/040-000 4AI 0-20mA S.E. /XTR

Device Description

3
The I/O module 750-453/040-000 (4AI 0-20mA S.E. /XTR) processed difference
signals from 0 mA ... 20 mA from the field range.
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.
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)".
For each channel, a red error LED indicates a measuring overrange.
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.
All field signals connected to this XTR I/O module must be powered by
SELV/PELV power supplies.
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.
