Safety Precautions
WARNING
Before removing, mounting, or wiring the NX-D15/25, be sure to turn off the power to the
module and all connected devices. Failure to do so might cause electricshock.
Be sure to check that the NX-D15/25 has been correctly wired before turning on thepower.
Incorrect wiring of the module can damage it or lead to hazardous conditions.
CAUTION
Tolock or unlock the DIN rail locking tab, use a tool such as ascrewdriver.
Do not disassemble the NX-D15/25. Doing so might cause electric shock or device failure.
Do not block the ventilation holes. Doing so might cause fire or devicefailure.
Do not allow wire clippings, metal shavings, water, etc. to enter the case of this device. They
can cause fire or device failure.
Do not touch electrically charged parts such as the power supply terminals. Doing so may
result in an electric shock.
Before wiring the NX-D15/25, be sure to disconnect thepower.
Failure to do so might cause device failure.
Wire the NX-D15/25 in compliance with established standards, using the specified power
source and recognized installation methods. Failure to do so could result in fire, electric
shock, or malfunction.
Ensure that the total power consumption of all linked modules does not exceed 100 W.
Otherwise fire or faulty operation could occur.
Do not supply power to the linked modules from multiple power sources. Doing so could
result in fire or malfunction.
Do not use unused terminals on the NX-D15/25 as relay terminals. Doing so might cause
electric shock, fire or device failure.
Do not short the output section. Doing so might cause devicefailure.
Firmly tighten the terminal screws to the torque listed in the specifications. Insufficient
tightening might cause fire.
If there is a risk of a power surge caused by lightning, use a surge protector to prevent
possible fire or failure of thedevice.
Use this device within the operating ranges given in the specifications (for temperature,
humidity, voltage, vibration, shock, mounting direction, atmosphere, etc.). Otherwise, fireor
device failure could result.
The NX-D15/25 does not operate for about 10 seconds after the power has been turned ON,
depending on the settings. Be careful if the output from the module is used as an interlock
signal.
When discarding the NX-D15/25, dispose of it as industrial waste, following local regulations.

Chapter 1. OVERVIEW
1 - 1 Overview and Features
■ Overview
■ Features
The Instrumentation Network Module uses Ethernet as standard to achieve
distributed instrumentation and high-speed communication, and reduce the required
wiring and engineering. This gives customers the value of improved environments,
quality and productivity.
The NX-D15/25 Controller Module is a module type of controller. One unit can perform up to
four loops of PID control.

● Engineering tools
Ethernet equipped as standard
Each module is equipped with an Ethernet communication function.
When modules are connected or distributed, the use of a daisy chain connection method
greatly reduces the required wiring.
Each module is also equipped with an RS-485 communication function. High-
speed communication is possible to devices such as host systems,
programmable logic controllers (PLCs) and display devices.
The system can be upgraded to the Yamatake Monitor and Control System.
Delivers a true distributed layout
When connected by Ethernet, the system can be used with a distributed layout that has
no functional differences from a connected layout.
Communication redundancy
Two communication configurations are available for the Ethernet network: non- ring and
ring.
Compact and highly functional
The body is an ultra-compact 30×100×104 mm.
Simple assembly
The three-part structure consists of a base, main body and terminal block. For ease of
operation, installation and removal can be performed without using any tools.
Connected operation and distributed layout
The input and output signals between modules can be linked. Also, modules used in a
distributed layout can be linked in the same way as during connected use.
Stand-alone operation is possible
Power, control and communication are integrated into a single unit. This enables efficient
use even for applications with low number of channels, and it also saves space.
One unit can perform up to four loops of PID control.
The input is a full multi-range input that allows settings to be freely set for the
thermocouple, resistance temperature detector (RTD), DC current and DC voltage.
The control mode supports 2-loop (with RSP) and heat/cool control.
The control output can be branched to control multiple final control elements. As an
option, up to four inputs or outputs can be mounted for one of the following: current
transformer, digital input or digital output.
Logical operation processes such as digital input, digital output and internal events
can be performed.
Linking modules enables operations that use inputs and outputs from other
modules.
The SLP-NX Smart Loader Package (sold separately) is available.
The Ethernet connection enables simultaneous connection to multiple modules. This
provides centralized management, setting and monitoring, which contributes to reduced
engineering requirements.
