Device Description

The Analog Input Module 753-454 (2AI 4-20mA Diff.) processes differential
signals with the norm value of 4 ... 20 mA.
The I/O module has 2 input channels for differential signals. The sensors may be
received via the CAGE CLAMP
The input channels have a common ground and a shield connection.
The shield connection is fed directly to the carrier rail and contact is made
automatically by snapping the module onto the rail.
The assignment of the connections is described in the "Connectors" section.
Connection examples are shown in section "Connecting Devices" > ... >
"Connection Example(s)".
The input signal is electrically isolated and is transmitted with a resolution of
12 bits.
The operational readiness and the trouble-free internal data bus communication of
the channels are indicated via a green function LED.
A red fault LED per channel indicates a wire break or that the signal is outside the
measuring range.
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.
Use a supply module!
Use a supply module for field-side power supply of downstream I/O modules.
Power to the internal electronics is supplied via internal data bus.
The I/O module 753-454 can be used with all fieldbus couplers/controllers of the
WAGO-I/O-SYSTEM 750 (except for the economy types 750-320, -323, -324
and -327).
