■ INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
POINTS OF CAUTION
■ HOT INSERTION/REMOVAL OF MODULES
• It is possible to replace the module with the power is sup-
plied. Be sure to replace it when the module is not com-
municating with a host, as it is possible to affect the sys-
tem. However, replacing multiple modules at once may
greatly change line voltage levels. We recommend that
you replace them one by one.
■ POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 120V AC rating: 85 – 132V, 47 – 66 Hz, approx. 20VA
200 – 240V AC rating: 170 – 264V, 47 – 66 Hz, approx. 20VA
24V DC rating: 24V ±10%, approx. 12W
■ GENERAL PRECAUTIONS
• DO NOT set the switches on the module while the power
is supplied. The switches are used only for maintenance
without the power.
■ ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -10 to +55°C
(14 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
■ WIRING
• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.

MODEL
■ AND ....
• The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.
INSTALLATION
Use the Installation Base Model R3-BS, or Model R3-BSW
for free I/O address capability.
Before mounting the Network Interface Module onto the
Base, be sure to configure the module as explained below.
■ DATA ALLOCATION
The setting determines the data area size assigned to each
I/O module mounted on the base.
The data sent/received via Modbus is mapped according to
this setting.
See "COMPONENT IDENTIFICATION" and "MODBUS
I/O ASSIGNMENTS".
■ NODE ADDRESS & BAUD RATE, ETC.
See "COMPONENT IDENTIFICATION".
■ NETWORK SLOTS ON THE BASE
I/O 1 I/O 2
With Model R3-BS base, mount the I/O Modules from the
left end (I/O 1) to the right in order that the Network Mod-
ule assigns data areas from I/O 1.
Network Module(s) and Power Module are mounted basi-
cally at the right end though technically they could be
mounted in any position.
With Model R3-BSW base, there is no limitation in mount-
ing positions as I/O address can be assigned freely to each
module using rotary switches equipped on the base.
