5.5 Jointing Each Module
Up to 29 modules (X-TIO-A/B, X-DI-A/B or X-DO-A/B) can be
connected to one X-TIO-G module.
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.

When viewed
from top
There is one joint tab at each
of the top and bottom of on
module. Therefore, fix two
adjacent modules with these
two joint tabs.

6. WIRING
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.
Power supply wiring must be twisted and have a low voltage 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).
In the maximum configuration (extension up to 30 modules) the
24 V DC supplied equipment may draw up to 4 A. The power
supply shall be capable of delivering at least 4 A.
Use the solderless terminal appropriate to the screw size.
- Screw size:
M3 x 6
- Recommended tightening torque: 0.4 N
m [4 kgf
cm]
- Specified solderless terminals:
With isolation
Make sure that during field wiring parts of conductors cannot
come into contact with adjacent conductive parts.

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
