 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 instrumen t 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 as a result of failure, protect

the power line and the input/output lines from high currents
with a suitable overcurrent protection device with adequate
breaking capacity such as fuse, circuit breaker, etc.

 Prevent metal fragments or lead w ire scraps from falling inside

instrument case to avoid electric shock, fire or malfunction.

 T ighten 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.

 When high alarm with hold act ion/re-hold action is use d for

Event function, alarm does not turn on while hold action is
in operation. Take measures to prevent overheating which
may occur if the control device fails.

for the actual program.

 Set the module address such that it is different to

the other addresses on the same line. Otherwise,
problems or malfunction may result.

4.2 Internal Data Bus Termination Resistor
Setting (PROFIBUS side)

Set the termination resistor of internal data bus for internal
communication.
When two or more modules are connected, set the internal data
bus termination resistors to ON in modules at both ends.
As a rule, as the X-TIO-G module is connected to the left end,
set the internal data bus termination resistor to ON (No.8 of DIP
switch 1: ON) on the PROFIBUS side and set that to OFF (No.8
of DIP switch 2: OFF) on the temperature control side.

6. WIRING

To prevent electric shock or instrument failure, do not
turn on the power until all wiring is completed. Make
sure that the wiring is correct before applying power to
the instrument.

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.

 Signal connected to Voltage input and Current input shall be

low voltage defined as “SELV” circuit per IEC 60950-1.

 If there is electrical noise in the vicinity of the instrument that

could affect operation, use a noise filter.

- Shorten the distance between the twisted power supply wire
pitches to achieve the most effective noise reduction.

- Always install the noise filter on a grounded panel. Minimize
the wiring distance between the noise filter output and the
instrument power supply terminals to achieve the most
effective noise reduction.

- Do not connect fuses or switches to the noise filter output
wiring as this will reduce the effectiveness of the noise filter.

Instrument power

 Power supply wiring must be tw isted an d have a lo w voltag e drop.
 For an instrument with 24 V power supply input, supply power

from "SELV" circuit defined as IEC 60950-1.

 A suitable power supply should be considered in end-use

equipment. The power supply must be in compliance with a
limited-energy circuits (maximum available current of 8 A).
