■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 SWAPPABLE MODULES
• Replacing the module does not affect other modules on
the same base. Thus, the module can be replaced while
the power is ON. However, replacing multiple modules
at once may greatly change live voltage levels. We highly
recommend to replace them one by one.
■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.
■UNUSED OUTPUT CHANNEL
• Close across the unused output terminals or set unused
channels to “unused” with PC Configurator software
(model: R3CON).
■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-BSx).

Unused channels left open are equal to the wire breakdown,
which turns the red ERR LED on and sets a burnout flag at
the PLC or the host device.
Unused channels can be specified and set so on the PC
Configurator Software (model: R3CON) without needing to
short at the field terminals.
• Unused Output Channels
Close across the unused output terminals as shown below.
*1. For dual redundant communication.
*2. To
use shield line, connect it to SLD terminal and ground the terminal 20.
Note: Do not use void terminals.

FUNCTIONS
■OUTPUT HOLD or OUTPUT OFF
In normal conditions, the module outputs the signal from
the preferred bus A.
When an error is detected, the output is switched to the
data from the bus B.
• Output Hold
If both are in error, the module holds the signal and stands
by until one of the communications recovers.
• Output OFF
If both are in error, the module outputs -15 % and stands by
until one of the communications recovers.
At the startup, it outputs -15 % until the communication is
established and normal data is received.
