BEFORE USE ....
Thank you for choosing us. Before use, please check con-
tents 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.
■PACKAGE INCLUDES:
Discrete output module ......................................................(1)
Mounter slider ....................................................................(2)
■MODEL NO.
Confirm Model No. marking on the product to be exactly
what you ordered.
■INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
POINTS OF CAUTION
■CONFORMITY WITH EU DIRECTIVES
• The equipment must be mounted inside the instrument
panel of a metal enclosure.
• The actual installation environments such as panel con-
figurations, connected devices, connected wires, may af-
fect the protection level of this unit when it is integrated
in a panel system. The user may have to review the CE
requirements in regard to the whole system and employ
additional protective measures to ensure the CE conform-
ity.
■POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
24V DC rating: 24V ±10%, approx. 60mA
■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, make
sure to turn off the power supply and output signal for
safety.
• 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 0 to 55°C (32
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 sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

MECHATROLINK RELATED COMMANDS
R7K4FML (Simple I/O) communicates with I/O service with no processor, therefore it uses a connectionless communication
protocol. There is no application layer either; the R7K4FML interchanges I/O data via data link layer.
■MECHATROLINK DATA LINK LAYER COMMAND DESCRIPTIONS
The following tables explain the two Commands supported by the R7K4FML.
