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.

Product description

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.

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

Product parameter

Dimensions:
Length = 5.75 inches, Height = 3 inches, Width = 3.76 inches
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.

Application field

Compact design

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. The Transducer Input Connectors, labeled “RESOLVER 1/2” and “RESOLVER 3/4” have eight contacts. The mating connectors are supplied with the NX2A4T-11. The AMCI part number for the mating connector is MS-8, while the Phoenix Contact part number is MSTB2.5/8-ST-5.08, order number 1757077.
The RESOLVER 1 / 2 connector is used for connecting to Single turn Transducers channels 1 and 2 or Multi turn Transducers channel 1. The RESOLVER 3 / 4 connector is used for connecting to Single turn
Transducers channels 3 and 4 or Multi turn Transducers channel 2.
The following table shows the connections between the NX2A4T-11 and the various resolver transducers that AMCI offers.
