Limit on Modules
・ Up to 10 modules consisting of GX90YD, GX90WD, and
GX90UT can be connected to the system.
・ One GX90WD module can be connected to each unit.
・ Two GX90YA modules can be connected to the main unit
and to the sub unit.
・ Up to 10 GX90YA modules can be connected to a GM10-1
system and up to 12 to a GM10-2 system.
・ If the measurement mode is High speed, a GX90XD or
GX90WD module can be connected to the system.
・ If the measurement mode is High speed, only GX90XA-
04-H0 (high-speed AI), GX90XD (DI), and GX90WD (DIO)
are detected. DI and DIO are fixed to remote mode.
Measurement and recording are not possible.
・ If the measurement mode is Dual interval, GX90UT is not
detected.
・ Up to 3 GX90UT modules can be connected to a GM10-1
system and up to 10 to a GM20-2 system.
Notes on Module Installation
• If you want to use reference junction compensation on a
thermocouple input of a GX90XA-10-U2, GX90XA-10-L1,
or GX90XA-10-T1, do not connect the following module to
the right of the GX90XA module as seen from the front.
Doing so may cause the reference junction compensation
accuracy to deviate from the guaranteed range.
GX90XA-10-C1 (for mA), GX90XA-04-H0 (high-speed AI),
GX90YA, GX90WD, GX90UT
• If the maximum number of I/O channels are assigned and
the last channel is assigned to an intermediate channel
of a connected I/O module, that module and subsequent
modules will not be identified.

• If you want to use the DI of a GX90XD or GX90WD, only a
single module installed in the GM main unit can be used.
• Do not link modules in a way that violates the
specifications. Doing so can cause the GM system to
crash. For details on the ways modules could be linked to
crash the GM system, see the User’s Manual.
Limitations depending on the Measurement Mode
Depending on the measurement mode, there are limits
to the number of measurement channels, the number of
recording channels, the supported modules, and so on.
For the specific limitations, see the limitations provided in
the following general specifications.
• GM Data Acquisition System General Specifications
(GS 04L55B01-01EN)
Channel Names
Operations such as measurement, computation, and
recording are performed on channels.
A channel name is assigned a 4-digit number consisting of a
unit number, slot number, and channel number.
• Channel names are specific to the system, so they cannot
be changed.
• By setting tags or tag numbers to the channels, you can
use any names you like.
