THE

 ANR2

AnyNET-I/O

The ANR2 is an expansion to the AnyNET-I/O product line from 
AMCI.  The concept of this product line is simple:  specialty and/
or high speed I/O that can be attached to any popular industrial 
network; hence the name 

AnyNET-I/O

. 

AnyNET-I/O is designed for a broad range of applications, from 
small machines with a single control enclosure, to large machines 
that use distributed I/O extensively to minimize wiring costs.

What makes the AnyNET-I/O line different is that all of the mod-
ules are available with or without a network interface.  Eliminating 
the need for a separate networking module lowers the total cost of 
ownership for all applications, but especially for the cost sensitive 
small machines that only require one or two sophisticated func-
tions.   

Like many modern controllers, AnyNET-I/O modules are 
designed to be DIN rail mounted. Up to six AnyNET-I/O modules 
can be stacked together and accessed over a single network inter-
face.  “Stacking” is accomplished through a small backplane con-
nector that snaps into the DIN rail before the AnyNET-I/O 
modules are installed.  These connectors allow the AnyNET-I/O 
modules to communicate with each other.  To the network, the 
stack of modules appear as one continuous block of I/O words.

The ANR2

The ANR2 is a two channel LVDT/RVDT signal conditioner module that accepts 24 Vdc as its power source.  
What makes the ANR2 unique is its advanced digital technology that completely eliminates all potentiometer 
adjustments and all but one jumper.   This technology allows the ANR2 to interface with half bridge sensors, 
as well as 3-, 4-, 5-, and 6-wire AC LVDT/RVDT sensors from any manufacturer with methods that eliminate 
many of the errors associated with changes in environmental temperatures.  The ANR2 offers 14 bit (16,386 
count) position resolution.

The elimination of jumpers and potentiometers means that you do not have to be physically near the ANR2 
while configuring and aligning it.  All configuration and alignment data is sent from your host system over 
the network connection of the AnyNET-I/O stack.  This allows you to:

Configure the ANR2 from anywhere

Store multiple setups on your machine, one for each type of sensor you use

Copy setup data from one machine to another

Design custom HMI interfaces for configuration and alignment that can simplify machine training, 
startup, and repair.

This manual assumes that you are familiar with LVDT/RVDT’s and their electrical character-
istics.  If you are not familiar with these sensors, please refer to Appendix A, 

The LVDT and 

RVDT

 starting on page 60.

This manual is designed to get you quickly up and running with the ANR2 LVDT/
RVDT Signal Conditioner Module.  It is possible to purchase an ANR2 with or with-
out a network interface.  This manual only covers the functionality unique to the 
ANR2.  Information on connecting to the network interface is available in the 
appropriate AnyNET-I/O Network Interface manual available on the AMCI website.
