BEFORE USE ....

POINTS OF CAUTION

Thank you for choosing us. Before use, please check contents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact our sales office or representatives.

■ GENERAL PRECAUTIONS• Before you remove the unit or mount it, turn off the power
supply and output signal for safety.
• Before you remove the terminal block or mount it, makesure to turn off the power supply and output signal forsafety.
• DO NOT set the switches on the module while the poweris supplied. The switches are used only for maintenancewithout the power.

■ PACKAGE INCLUDES:
Remote control relay control module..................................(1)■ MODEL NO.
Confirm Model No. marking on the product to be exactly
what you ordered.
■ INSTRUCTION MANUALThis manual describes necessary points of caution when
you use this product, including installation, connection andbasic maintenance procedures.
■ EDS FILE
EDS files are downloadable at our web site.

■ ENVIRONMENT• Indoor use.
• When heavy dust or metal particles are present in theair, install the unit inside proper housing with sufficientventilation.
• 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.
• Be sure to close the terminal cover for safety.
■ AND ....
• The unit is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required forsatisfying complete performance described in the datasheet.

Baud Rate Setting

The R7D communicates in the baud rate setting detected at
the startup with the switch set to the positions 0 (125 kbps),1 (250 kbps) or 2 (500 kbps).
For the settings 3 through 9, it analyzes the PLC’ s network
to determine the baud rate on the network.

R7D-RR8INPUT OUTPUT DATA BIT & DATA ALLOCATION
Output data length can be set with the front DIP switch. Input data length is regardless of output data length, feedback
inputs 1 to 8 are assigned to bit 0 to 7.
Input ON: 1, Input OFF: 0■ OUTPUT DATA BIT: 16 BITS (SW1-3: OFF)
When output data bit is 16 bits, set each output with 2 bits.
The table below shows data allocation.

UnusedUnusedUnusedUnusedUnusedUnusedUnusedUnusedON (or OFF) cannot be set consecutively, because wheneach bit is “1”, ON is set and when each bit is “0”, OFF is set.

By setting with 2 bits, the module operates as shown above.
ON or OFF can be set consecutively. To output ON twice
successively, set ON (1, 0), RESET (1, 1), and then set ON(1, 0) again.

DATA ALLOCATION‘Begin’ address is determined by the R7D’s node address and the master setting.
