NX2A4T-11  Four Channel Modbus TCP/IP Resolver Input Module

The AMCI NX2A4T-11 is a four resolver input module that communicates on Modbus TCP/IP. The four
resolvers connected to this module can be configured as four single turn transducers, two single turn
transducers and one multi turn transducer, or two multi turn transducers.
This unit has two discrete inputs labeled Brake and Preset. The Brake Input is used to capture the
current channel 1 position and the Preset Input is used to Apply the programmed Preset Value to the
channel 1 position data. Both of these inputs can be programmed to act on the 0 to 1 (off to on) and or
the 1 to 0 (on to off) transitions of the inputs. Please note that any changes made to the channel 1
position data by the preset input are not saved through power down. However, Apply Preset operations
performed over the network are saved through power down.
The NX2A4T-11 uses 21 input and 10 output words to communicate on Modbus TCP/IP.

Mounting
The NX2A4T-11 can be panel mounted in two ways, either on a DIN rail or panel mounted. The
mounting kit, included with the unit, contains two DIN brackets, two panel brackets, and four #8 screws
needed to attach your choice of brackets to the NX2A4T-11. Note that the enclosure is not sealed and
the NX2A4T-11 must be installed in an adequate enclosure to protect it from environmental
contaminates.
Attaching the DIN Brackets
The following figure shows how to install the DIN brackets so that the NX2A4T-11 can be mounted on
EN 50 022 or EN 50 035 rail. Note that the bottom view of the unit is shown. The rear view is similar
and the brackets are installed in the same fashion.
