Device Description

The 750-471 I/O Module 750-471 (4AI U/I Diff Galv) processes differential current
and voltage signals from the field:
• 0 ... 10 V
• ± 10 V
• ± 200 mV
• 0 ... 20 mA
• 3,6 ... 21 mA NE43
• 4 ... 20 mA
• ± 20 mA
The I/O module has four electrically isolated input channels for differential
signals. The sensors are connected to the CAGE CLAMP® terminals +AI1 and
−AI1, +AI2 and −AI2, +AI3 and −AI3, +AI4 and −AI4.
The assignment of the connections is described in the "Connectors" section.
Connection examples are shown in section "Connect Devices" > ... >
"Connection Example(s)".
The input signal is electrically isolated and transmitted with a resolution of 16 bits.
The operational readiness and the trouble-free local bus communication of the
channels are indicated via a green function LED.
A red fault LED per channel indicates that the signal is outside the measuring
range and depending on the type of signal additionally an overload or a wire
break.
Details about the individual signal types are described in the "Process Image" >
"Process Data" 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 750-471 module can be used with the fieldbus couplers and controllers of
the WAGO-I/O-SYSTEM 750 of the specified version or higher listed in the
"Compatibility list" table.
