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:
Signal conditioner (body + base socket) ..................... (1)
■ MODEL NO.
Check that model No. described on specification label is
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 EC DIRECTIVES
• This equipment is suitable for use in a Pollution Degree 2
environment and in Installation Category II, with the maximum operating voltage of 300V.
Basic insulation is maintained between the signal input and
output. Prior to installation, check that the insulation class
of this unit satisfies the system requirements.
• Altitude up to 2000 meters
• The equipment must be mounted inside a panel.
• Insert a noise filter for the power source connected to the
unit. Densei-Lambda Noise Filter Model MZS-1206-33 or
equivalent is recommended.
• The actual installation environments such as panel configurations, connected devices, connected wires, may affect
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 conformity.
■ POWER INPUT RATINGS
• Operational range & power consumption: Check the power
rating for the unit on the specification label.
Rating 100 – 240V AC: 85 – 264V, 47 – 66 Hz, approx. 10VA
Rating 12 – 24V DC: 10.8 – 26.4V, approx. 4W
Rating 110V DC: 85 – 150V, approx. 4W
• Power fuse: A power fuse of the rating as shown below is
incorporated for safety. However, DO NOT replace it by the
user.
AC rating and 110V DC: T 0.5A 250V
DC rating except 110V DC: T 1A 250V
■ UNPLUGGING THE UNIT
• Before you remove the unit from its base socket or mount it,
turn off the power supply and signal input for safety.
DA3
■ 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 -5 to +55°C (23
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 (power supply, input and output) close
to noise sources (relay drive cable, high frequency line, etc.).
• Do not bind the unit's cables together with cables where
high noise levels are present. Do not install them in the same
duct.
■ AND ....
• The unit is designed to function as soon as power is
supplied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data sheet.

INSTALLATION
Detach the yellow clamps located at the top and bottom of the
unit for separating the body from the base socket.
■ DIN RAIL MOUNTING
Set the base socket so that its
DIN rail adaptor is at the bottom. Position the upper hook
at the rear side of base socket
on the DIN rail and push in the

CHECKING
LIGHTNING PROTECTION
1) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal 7
– 8 with a multimeter.
3) Input: Dry contact or open collector. Check the input
device meets the following requirements.
TTL level
Sensing: 5V DC @1mA
Threshold voltage of the input circuit: 1V DC
24V DC
Sensing: 24V DC @3.5mA
Threshold voltage of the input circuit: 3V DC
LOAD signal: ON time 1 millisec. min.
4) Output: Check that the load resistance meets the described specifications.
In order to protect the unit from lightning surges entering
through power supply cables, use of appropriate lightning
surge protectors are recommended. Please contact M-System.
