CAUTION
z
This instrument is protected from electric shock by
reinforced insulation. Provide reinforced insulation between
the wire for the input signal and the wires for instrument
power supply, source of power and loads.
z
Be sure to provide an appropriate surge control circuit
respectively for the following:
If input/output or signal lines within the building are
−
longer than 30 meters.
If input/output or signal lines leave the building,
−
regardless the length.
z
This instrument is designed for installation in an enclosed
instrumentation panel. All high-voltage connections such
as power supply terminals must be enclosed in the
instrumentation panel to avoid electric shock by operating
personnel.
z
All precautions described in this manual should be taken to
avoid damage to the instrument or equipment.
z
All wiring must be in accordance with local codes and
regulations.
z
All wiring must be completed before power is turned on to
prevent electric shock, instrument failure, or incorrect
action.
The power must be turned off before repairing work for
input break and output failure including replacement of
sensor, contactor or SSR, and all wiring must be
completed before power is turned on again.
z
To prevent instrument damage or failure, protect the power
line and the input/output lines from high currents with a
protection device such as fuse, circuit breaker, etc.
z
Prevent metal fragments or lead wire scraps from falling
inside instrument case to avoid electric shock, fire or
malfunction.
z
Tighten each terminal screw to the specified torque found
in the manual to avoid electric shock, fire or malfunction.
z
For proper operation of this instrument, provide adequate
ventilation for heat dispensation.
z
Do not connect wires to unused terminals as this will
interfere with proper operation of the instrument.
z
Turn off the power supply before cleaning the instrument.
z
Do not use a volatile solvent such as paint thinner to clean
the instrument. Deformation or discoloration will occur. Use
a soft, dry cloth to remove stains from the instrument.
z
To avoid damage to instrument display, do not rub with an
abrasive material or push front panel with a hard object.
z
Do not connect modular connectors to telephone line.

3. PARTS DESCRIPTION
Two types of digital output (DO) module are available: the
X-DO-A with 12 output channels (terminal block only) and the
X-DO-B with 28 output channels (12-point terminal block/
16-point connector).
As the
digital output
(DO) module is not provided with terminals
for power supply and host communication, it is always used
together with the module (temperature control module [basic
type] X-TIO-A, etc.) with terminals for power supply and host
communication.

•
noise.
Direct air flow from an air conditioner.
•
Exposure to direct sunlight.
•
Excessive heat accumulation.
•

6. WIRING
p
To prevent electric shock or instrument failure, do
not turn on the power until all the wiring is
com
leted.
CAUTION
To avoid noise induction, keep input signal wire away from
instrument power line, load lines and power lines of other
