The NX2A4E2
The NX2A4E2 is a member of the growing line of products from AMCI that incorporate our E2 Technology .
E2 Technology by AMCI is an innovative new multi-protocol approach to Ethernet distributed I/O.
E2 Technology products are simple and intuitive, allowing easy transition between Ethernet/IP, PROFINET,
or Modbus/TCP protocols without the need to physically switch parts. An advanced web server integrated
into all AMCI E2 Technology devices facilitates simple network configuration and troubleshooting via a
web-browser. Furthermore, an impressive array of advanced features for each supported protocol has been
incorporated into the devices to meet many unique application requirements.
The NX2A4E2 is a four channel resolver interface module that allows you to lower transducer wiring cost by
placing the NX2A4E2 close to the transducers and running a single network cable back to the host controller.
The NX2A4E2 also future-proofs your resolver feedback design. The host controller can be updated to any
future platform that supports EtherNet/IP, PROFINET, or Modbus TCP and the NX2A4E2 will operate with
the new system.
The NX2A4E2 can be programmed to accept up to four single resolver transducers, or two dual-resolver
transducers. Single resolver transducers are typically single turn devices, but can have a gear train between
the input shaft and the internal resolver. Dual-resolver transducers are designed for high resolution, multi-turn
applications. The NX2A4E2 can also be programmed to accept two single resolver transducers and one dual-
resolver transducer. This setup is advantageous in several industries, such a press automation. This unit gives
press builders crankshaft angle indication on a single-turn channel and shut height indication on the multi-
turn channel, combining the functions of two separate boxes or modules into one. To further aid press integra-
tors, the NX2A4E2 also includes a brake input that can be used to measure crankshaft stopping time.
Each unit has two Ethernet ports which are internally connected through an onboard, two port, 10/100 Mbps
ethernet switch. These ports allow you to wire your network in a “daisy-chain” fashion, which may lower net-
work wiring costs and complexities.
The two ports also allow the units to function as members of a redundant Device Level Ring (DLR) network
when using the EtherNet/IP protocol or as clients in a Media Redundancy Protocol (MRP) network when
using PROFINET.
In DLR environments, the units act as Beacon-Based Ring Nodes. All units can process beacon packets at the
default rate of every 400 microseconds. Beacon-based nodes can respond faster to network changes than
nodes that only process Announce packets.
