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)
Surface 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 con-
formity.
* For example, installation of noise filters and clamp fil-
ters for the power source, input and output connected
to the unit, etc.
■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%, ≤ 70 mA
■GENERAL PRECAUTIONS
• Before you remove the unit or mount it, turn off the power
supply and I/O signal for safety.
• Before you remove the connector or mount it, make sure
to turn off the power supply and I/O signal for safety.
■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.
■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.

0 : Normal
1 : Detected the overcurrent/overheat and disconnection
Note: Status is disabled with option code /D1 (without wire breakdown detection).
When overcurrent or overheat is detected on each channel of discrete output while the output is ON, the status bit correspond-
ing to the output turns “1” and is latched*. Then the discrete output is also latched to OFF.
To reset the latched bit and discrete output, set this output to OFF from the host PC/PLC or turn off and on the power supply
to the unit.
When disconnection (open load) is detected while output is OFF, the corresponding status bit turns “1” but is not latched.
* The status bit turns “0” if the load is opened in the state overcurrent or overheat is detected. However, the discrete output of the
unit remains latched. Be sure to remove the cause of error and reset the latched output by setting the output to OFF or turning
off/on the power supply.
