INSTRUCTION MANUAL
BEFORE USE ....
Thank you for choosing M-System. 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 M-System’s Sales Office or representatives.
■PACKAGE INCLUDES:
Discrete I/O module ............................................................(1)
■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.
• Install lightning surge protectors for those wires connect-
ed to remote locations.
■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. 40mA
■GENERAL PRECAUTIONS
• Before you remove the unit or mount it, turn off the power
supply, input and output signal for safety.
• Before you remove the terminal block or mount it, turn
off the power supply, input 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 -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.
• Be sure to close the terminal cover for safety.
■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 sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet

EXAMPLE OF OPERATION MODES
■MAINTAINED OUTPUT MODE
Example of Y0 is shown below.
Bit 0 OFF

Y0
■MOMENTARY OUTPUT MODE
Y0 and Y1, Y2 and Y3, Y4 and Y5, Y6 and Y7 are respectively combined to realize momentary switching with one-shot output.
Bit 0, 2, 4, 6 are used to control each set of outputs, while Bit 1, 3, 5, 7 are unused.
An example of Bit 0 controlling Y0 and Y1 outputs sequentially is shown below.
1) Output data Bit 0 is turned from 0 to 1.
2) Following the rising edge of Bit 0, Y0 one-shot output turns ON for a fixed period of time (SW1 time setting).
3) Bit 0 is turned from 1 to 0.
4) Following the sinking edge of Bit 0, Y1 one-shot output turns ON for a fixed period of time (SW1 time setting).

Note: If Bit 0 receives multiple data during the one-shot output time period, the Y0 provides only the last output data received
within approx. 25 milliseconds after the period.
