with a module fixing screw. (Q68TD-G-H01 only)
●Tighten the screw within the specified torque range.
Undertightening can cause drop of the screw, short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
●Shut off the external power supply (all phases) used in the system before mounting or removing the
module.
Failure to do so may result in damage to the product.
A module can be replaced online (while power is on) on any MELSECNET/H remote I/O station or in
the system where a CPU module supporting the online module change function is used.
Note that there are restrictions on the modules that can be replaced online, and each module has its
predetermined replacement procedure.
For details, refer to the relevant chapter in this manual.
●Do not directly touch any conductive parts and electronic components of the module.
Doing so can cause malfunction or failure of the module.
CAUTION

The Q68TD-G-H02(H01) is a module designed to convert thermocouple input values from
outside the programmable controller into 16-bit signed binary measured temperature
values and 16-bit signed binary scaling values (ratios).

1- 2 1.1 Features
1OVERVIEW
1.1 Features
(1) Channels isolated
Q68TD-G-H02(H01) is channel isolated modules.
(2) 8 channels of temperatures measured by one module
One Q68TD-G-H02(H01) module can measure temperatures of 8 channels.
It can also convert the detected temperature values into scaling values (ratios (%)).
(3) Setting of conversion enable/disable
Conversion enable/disable setting for each channel is possible. Disabling conversion
for unused channels prevents unnecessary disconnection detection or monitor of
disconnection state on unused channels.
(4) Use of thermocouples conforming to JIS or IEC standards
Eight types of thermocouple (K, E, J, T, B, R, S, N) conforming to JIS or IEC standards
can be used.
A thermocouple type can be selected for each channel.
(5) Disconnection detection function (Q68TD-G-H02 only)
Disconnection status of thermocouple or compensating lead wire can be detected for
each channel by Disconnection detection flag.
Disconnection status can also be detected from the measured temperature value by
setting "Up scale", "Down scale" or "Given value" for the Conversion setting for
disconnection detection.
(6) Disconnection monitor function (Q68TD-G-H01 only)
Disconnection status of thermocouple or compensating lead wire can be checked on
each channel by Disconnection state monitor flag.
Disconnection status can also be checked from the measured temperature value by
setting "Up scale", "Down scale" or "Given value" for the Conversion setting for
disconnection detection.
(7) Selection of sampling processing, time average processing, count average
processing, moving average processing, and primary delay filter
As a conversion processing method, sampling processing, time average processing,
count average processing, moving average or primary delay filter can be selected for
each channel.
(8) Cold junction temperature compensation by cold junction temperature
compensation resistor (RTD)
Cold junction temperature compensation is possible by connecting the supplied cold
junction temperature compensation resistor (RTD) and enabling the cold junction
temperature compensation.
Resistance temperature detector Pt100 is used for cold junction temperature
compensation resistor (RTD).

(9) Error compensation by offset/gain value setting
Error compensation can be made by setting offset and gain values on each channel.
As the offset and gain values, you can make selection from user range setting and
factory default setting.
(10)Warning output function
(a) Process alarm warning output
A warning can be output when the input range set by the user is exceeded.
Upper limit value and lower limit value can be set for each channel, and a setting
to have a difference (hysteresis) between warning output and warning clear is
also possible.
(b) Rate alarm warning output
By setting a changing rate, a warning can be output when the changing rate is
exceeded.
(11)Online module change
The module can be changed without stopping the system.
Furthermore, the following operations can be processed by using sequence
programs.
• Transferring the offset/gain set values to the replacement Q68TD-G-H02 (H01)
• Transferring the offset/and gain set values to another Q68TD-G-H02 (H01)
mounted on the other slot
(12)Easy settings using GX Configurator-TI
Using GX Configurator-TI which is sold separately, sequence programs can be
reduced since settings of the Q68TD-G-H02 (H01) can be made on the screen.
Also, the set status or operating status of the module can be checked easily.
