DESCRIPTION |
|
 The
AMCI NR25 series of heavy-duty Modbus-TCP Resolvers are compatible
with all PLCs/PACs that support Modbus-TCP . The NR25 series
networked resolvers are available in absolute single-turn
and multi-turn packages using an IP67 rated 2.5" size
industrial housing. Solid shaft and hub shaft styles are available
to suit various mounting requirements. These Modbus-TCP absolute
rotary resolvers provide up to 30 bit total resolution, delivering
16 bit (65536 steps) per revolution and up to an additional
14 bit (16384 revolutions) for multi-turn versions.
Easy To Configure & Install
AMCI's Modbus-TCP TCP/IP encoders are designed for simple set-up
and trouble free performance. The NR25 networked encoders are
compatible with all PLCs and PACs that support Modbus-TCP, including
Schneider Modicon controllers. Programmed using Rockwell Automation's
RSLogix software or Schneider's Unity Pro software ensures hassle
free integration with your application. Plus, addressing the
AMCI NR25 Modbus-TCP encoder on your network is easy and convenient
using our MS Windows-based Enet Configuration software utility
(included at no charge).
The NR25 Modbus-TCP resolvers offer a variety of programmable features:
- Selectable Resolution
- Selectable Count Direction
- Selectable Velocity Format
- Programmable Presets for Zeroing or Homing
All programmable parameters and the preset offset are stored
in the internal non-volatile memory for speedy retrieval,
making it quick and easy to configure your NR25 Modbus-TCP TCP/IP
resolver.
Power over Ethernet (PoE)
AMCI's NR25 Modbus-TCP resolver comes standard with Power
over Ethernet (PoE), making it possible to install this resolver
using a single Ethernet cable that transmits data AND
power! Your connector and cabling requirements are cut in
half, plus installation is simpler and less expensive. The
Power over Ethernet feature allows you to use AMCI's NR25
resolver in applications where utilizing a traditional DC
power supply would be inconvenient, plus all of these advantages:
- NR25 only requires a single Ethernet cable for power/data
transmission.
- NR25 placement is flexible, and no longer limited to nearby
power sources.
- NR25 can be easily moved to wherever there is LAN cabling.
- NR25 and a UPS can guarantee up time during main failures.
- NR25 can be shut down or reset remotely.
- NR25 requires little configuration or management.
NOTE:
NR25 end connector units allow customers to either use separate
network and auxiliary power connections, or a single Ethernet
cable/connection to transmit data and power using Power over
Ethernet (PoE).
NR25 side connector units are only available with Power over
Ethernet (PoE), using a single Ethernet cable to transmit
data and power.
Heavy-duty Performance & Reliability
The NR25 networked resolver is resolver
based and supplies absolute position feedback without
glass discs or sensitive LED components, enabling it to withstand
high levels of shock and vibration. The IP67 rated housing
guarantees protection against dust and water ingress. Add
the NR25 Modbus-TCP resolver's impressive shaft load ratings
and ruggedness is second to none.
AMCI's NR25 Modbus-TCPnetworked resolver is the heavy-duty
solution for single-turn and multi-turn position applications
requiring serious reliability for today's harshest industrial
environments.
