WARNING
!
CAUTION
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.
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.
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.
All precautions described in this manual should be taken
to avoid damage to the instrument or equipment.
All wiring must be in accordance with local codes and
regulations.
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.
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.
Prevent metal fragments or lead wire scraps from falling
inside instrument case to avoid electric shock, fire or
malfunction.
Tighten each terminal screw to the specified torque found
in the manual to avoid electric shock, fire or malfunction.
For proper operation of this instrument, provide adequate
ventilation for heat dispensation.
Do not connect wires to unused terminals as this will
interfere with proper operation of the instrument.
Turn off the power supply before cleaning the instrument.
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.
To avoid damage to instrument display, do not rub with
an abrasive material or push front panel with a hard
object.
Do not connect modular connectors to telephone line.

3. PARTS DESCRIPTION
One temperature control (TIO) module [extension type] enables
temperature control corresponding to two channels.
As the temperature control (TIO) module [extension type] 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.
The temperature control (TIO) module [extension type] can be
connected with the temperature control (TIO) module [basic
type], the temperature control (TIO) module for PLC
communication, the digital input (DI) module and the digital
output (DO) module.
All data are set by communication. For details, see the
Module Type Controller SRX Communication
Instruction Manual (IMS01N01-E).

(Absolute humidity: MAX. W. C 29 g/m
(3) Avoid the following when selecting the mounting location:
• Rapid changes in ambient temperature, which may cause
condensation.
• Corrosive or inflammable gases.
• Direct vibration or shock to the mainframe.
• Water, oil, chemicals, vapor or steam splashes.
• Excessive dust, salt or iron particles.
• Excessive induction noise, static electricity, magnetic fields or
noise.
• Direct air flow from an air conditioner.
• Exposure to direct sunlight.
• Excessive heat accumulation.
(4) Mounting consideration
• Install the module 200 mm away from the main power line.
• Ensure at least 50 mm space on top and bottom of the
control unit for maintenance and environmental reasons.

5.5 Jointing Each Module
Up to 31 SRXs consisting of the each modules can be jointed
together. Joint these modules according to the following
procedure.
Jointing procedure
1. Mount the modules on the DIN rail and then joint these
modules together with the joint connector while sliding the
relevant module.
2. Lift each of the joint tabs located at the top and bottom of the
module and then insert it in the slot of the adjacent module to
fix these two modules.
For panel mounting, first joint each module and then
mount it on the panel.

6. WIRING
To prevent electric shock or instrument failure, do
not turn on the power until all the wiring is
completed.
6.1 Wiring Cautions
For thermocouple input, use the appropriate compensation
wire.
For RTD input, use low resistance lead wire with no
difference in resistance between the three lead wires.
To avoid noise induction, keep input signal wire away from
instrument power line, load lines and power lines of other
electric equipment.
