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.

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
z
For thermocouple input, use the appropriate compensation
wire.
z
For RTD input, use low resistance lead wire with no
difference in resistance between the three lead wires.
z
To avoid noise induction, keep input signal wire away from
instrument power line, load lines and power lines of other
electric equipment.
z
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.
z
Power supply wiring must be twisted and have a low voltage
drop.
z
For an instrument with 24 V power supply, supply power from
a SELV circuit.

•
Terminal No. 11 is not used.
•
Input channel 2 can be used as remote setting input
(only for voltage/current input).
In this case, control output 2 and CT input 2 become
unused.
•
Use the solderless terminal appropriate to the screw
size (M3)
.
