POINTS OF CAUTION

■ POWER INPUT RATING & OPERATIONAL RANGE

• Locate the power input rating marked on the product and
confirm its operational range as indicated below:

100 – 240V AC rating: 85 – 264V, 47 – 66 Hz,
approx. 15VA at 100V AC
approx. 20VA at 200V AC
approx. 21.5VA at 240V AC

24V DC rating: 24V ±10%, approx. 8.5W

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.

• Attachment and adjustment of sleeve antenna: Loosen
the connector (See the below figure), and rotate the an­tenna. Holding the antenna vertically, tighten the connec­tor by hand. Make sure to fix the antenna firmly.

• Attachment of rooftop antenna: The magnet on the bottom
face allows the antenna to be attached on a metal box and
such. To obtain optimum performance from the antenna,
attach it on a metal plate (recommended dimension: 500
mm × 500 mm or more). However, in the case of connect­ing FE1 or FG of the power supply module to a metal
plate, the isolation between FE1 or FG and the internal
bus or internal power or antenna connector will be lost.
Tighten the connector with a specified torque (0.9 N∙m).
As a guide, finger-tighten the connector until it stops, and
then rotate it 10 to 15 degrees with a wrench. Do not force
the cable to bend beyond the acceptable bending radius
of 3 cm.

• Please note that using 7.5 m coaxial cable (model: CX­SAC0SAD0Q0750) (OKI) for extension decreases trans­mission distance.

■ HOT-SWAPPABLE MODULES

• The module can be replaced while the power is ON. Be
sure to replace it when the module is not communicat­ing with a host, as it may affect the system. Replacing
multiple modules at once may greatly change line voltage
levels. We highly recommend to replace them one by one.

■ ENVIRONMENT

• Indoor use.

• Attach the antenna to the unit.

• When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.

■ 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.

■ AND ....

• The unit is designed to function as soon as power is sup­plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

for free I/O address capability.

Before mounting the Network Interface Module onto the
Base, please do the following.

■ DATA ALLOCATION

Set the DIP switches (SW1, SW2) so as to assign the data
area size to each I/O module mounted on the base.
The data sent/received via Modbus is mapped according to
the setting.
See “COMPONENT IDENTIFICATION” and “MODBUS
I/O ASSIGNMENTS.”

■ MOUNTING TO THE BASE

I/O 1 I/O 2 I/O n

■ FCC RF EXPOSURE INFORMATION

• This equipment complies with FCC radiation exposure
limits set forth for an uncontrolled environment and
meets the FCC radio frequency (RF) Exposure Guide­lines. This equipment should be installed and operated
keeping the radiator at least 20 cm or more away from
person’s body.

FCC ID: 2AOTF-0000009 (24 V DC)
FCC ID: 2AOTF-0000010 (100 – 240 V AC)
Contains FCC ID: 2AKGW-1TD3016A1

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 Mod­ule assigns data areas from I/O 1.
Network Module(s) and Power Module are mounted basi­cally at the right end though technically they could be
mounted in any position.

With Model R3-BSW base, there is no limitation in mount­ing positions as I/O address can be assigned freely to each
module using rotary switches equipped on the base.

I/O DATA DESCRIPTIONS

The data allocations for typical I/O modules are shown below.
Refer to the manual for each module for detailed data allocations.

■ ANALOG DATA (16-bit data, models: R3-SV4, YV4, DS4, YS4 and US4, etc.)

16-bit binary data.
Basically, 0 to 100% of the selected I/O range is converted into 0 to 10000 (binary).

-15 to 0 % is a negative range represented in 2’s complement.
In case of R3-US4, -10 to 0% is a negative range represented in 2’s complement.

15

■ TEMPERATURE DATA (16-bit data, models: R3-RS4, TS4 and US4, etc.)

16-bit binary data.
With °C temperature unit, raw data is multiplied by 10. For example, 25.5°C is converted into 255.
With °F temperature unit, the integer section of raw data is directly converted into the data. For example, 135.4°F is con­verted into 135.
Minus temperature is converted into negative values, represented in 2’s complements.

0

15

0

■ ANALOG DATA (16-bit data, models: R3-CT4A, CT4B, etc.)

16-bit binary data.
Integer obtained by multiplying unit value (A) by 100.
In case of CLSE-R5, integer obtained by multiplying unit value (A) by 1000.

(1) (2) (3) (4) (5)

1) When the main/sub switching control for both main and sub network is set to ‘0’, all contact outputs are off, and analog
output modules output -15%.

2) When the main’s setting is switched to ‘1’, the output modules are in control of the main host device.

3) When a loss of communication is detected in the main network, the output signal is held for the preset time period. (Timer
is programmable with the PC Configurator Software, R3CON.) After the time has elapsed, the output control is switched
from the main to the sub network. Be sure to set an appropriate output signal to the sub network and switch the sub’s
setting to ‘1’ before such switching occurs.

4) The output modules’ control is not automatically switched back to the main’s when the main network is restored if the
main’s setting is ‘0’. Thus, if the main’s setting is ‘1’, the control is back to the main’s.

5) When both the main and the sub network modules are in communication, the output can be switched without delay.
