Features of KT4R, KT8R and KT9R
Smooth initial setting and setting adjustment
Fine control of heat capacity
Operation startup can begin after using initial setting mode to enter
the control values required before first use, and after entering values
for items such as frequently used and frequently changed settings.
Smooth operation is enabled at initial startup and after changing
settings.
Sampling period rate half (1/2 times) from previous model: high speed
125 ms processing implemented. With twice the responsiveness, it
is possible to more finely carry out control, for example, of the heat
capacity.
Built-in easy programming function
Built-in rearing auto tuning function
Easy programmed control made possible using nine-step setting
procedure. By entering specific target values for each indicated period,
freely selectable temperature control is possible.
The built-in rearing auto tuning function uses the step response
method. From temperature rise behavior alone, it can calculate the PID
constants. It is possible to calculate constants, even when auto tuning
cannot be used to generate them.
Because an ON / OFF operation is unnecessary, there is no disruption
in control.
Example: From start of programmed control
Perform control so it becomes 200 °C 392 °F after 1 hour.

•V
isibility and operability improved with large display and key size.
• Unit 60 mm 2.362 in approx. long: compact design saves space.
• With DC current output, can be used as simple signal converter.
Shared features of KT series
Multi-input sensors
Versatile thermocouple, RTD, DC voltage and DC current input for
temperature detecting sensors
Simple operation enables highly accurate temperature control
All required operations can be enabled by the front keys and highly
accurate PID control mode ensures an input span of ±0.2 %.
DIN Rail mounting types are aligned taking global
market demand into consideration (for KT7 series)
Improved visibility and ease of operation
More compact than before
The KT4H / KT4B series features improved visibility with a process
value (PV) character height of 12 mm 0.472 in and an 11-segment
display. Connectable to a PC, it offers a full range of control and
communication functions.
Communication specification uses RS485 (Modbus protocol)
(Sample System Configuration)
FPΣ Programmable Controller
The KT7 series is equipped with DIN rail mounting complying to DIN
standards. Furthermore, because its control panel is compact, the KT7
series saves space.
Nine step pattern control possible. (for KT2 series)
RS485
For KT2 series, despite DIN 48 x 24 size, selection is possible of
control with fixed set point and nine step pattern control.
Meets market demands for cost-effectiveness
The KT series offers both economy and high performance.
The KT series complies with UL/c-UL standard and CE marking.

Up to 31 units can be connected
*1 Only on type equipped with communications function.
*2 In the configuration above, the FPΣ requires a communication cassette (FPG-COM3).
*3 Modbus protocol is a communication protocol developed for PLCs by Modicon Inc.

Notes: 1) Shielded cable
To prevent current flow along shield sections, ground one end of the shield cable.
(If both ends of the shield section are grounded, a closed circuit with the earth will form
and electricity flowing through the shield cable will cause increased susceptibility to
noise.)

KT SERIES Temperature Controller
NOTES FOR USE
n Notes on site selection
This controller is intended to be used in the following
environment (IEC 61010-1)
•O
vervoltage category II and Pollution degree 2
Mount the controller in a place with:
• A minimum of dust, and an absence of corrosive gases
• No flammable, explosive gases
•F
ew mechanical vibrations or shocks
• No exposure to direct sunlight, an ambient temperature of
0 to 50 °C 32 to 122 °F (For KT4R / KT8R / KT9R: -10 to 55 °C
14 to 131 °F) that does not change rapidly. (When installing
inside a panel, make particular allowance for heat dissipation.
Avoid installation in situations such as above equipment that
generates heat.)
•L
ocations in which temperature rapidly changes may cause
condensation.
•L
ocations or atmospheres in which benzine, thinners, alcohol,
or other organic solvents are present, or in which ammonia,
sodium hydroxide, or other strong alkaline substances may
adhere.
• Locations susceptible to direct impact or the transmission of
vibrations, or where splashing with water is possible.
• In the proximity of equipment in which large switching surges
occur or near high-voltage cables, high-voltage equipment,
power lines, power equipment, ham radio transmitters, or
equipment containing these or similar devices.
• An ambient non-condensing humidity of 35 to 85 % RH
• No large capacity electromagnetic switches or cables through
which large current is flowing
• No water, oil or chemicals or where the vapors of these
substances can come into direct contact with the controller
n Notes on wiring
• The terminal block of KT4R / KT8R / KT9R / KT4H / KT4B series
are designed to be wired from the left side (The terminal of
KT2 series are designed to be wired from the upper and lower
direction). The lead wire must be inserted from the left side of
the terminal, and fastened by the terminal screw. Use a wirepressed terminal with insulation sleeve that fits to the M3 screw.
• In the case of 24 V AC / DC power supply, do not confuse the
polarity when it is DC.
•W
ith the relay contact output type, use the relay externally
according to the capacity of the load to protect the built-in relay
contact.
•W
hen wiring, keep input wire (Thermocouple, RTD, etc.) away
from power source wire and load wire.
•T
urn the power supply to the instrument off before wiring or
checking. Working or touching the terminal with the power
switched on may result in electric shock which could cause
severe injury or death.
•D
o not drop wire chips into the holes of vent when wiring.
•T
o prevent the controller from harmful effects of unexpected
high level noise, it is recommended that a surge absorber be
installed between the electromagnetic switch coils.
n Notes on mounting
• Do not use excessive force while screwing in the installation
frame and mounting bracket of KT4R / KT8R / KT9R / KT4H /
KT4B series. For KT8R / KT9R series, recommended torque is
approximately 0.1 N·m. For KT4H / KT4B series, recommended
torque is approximately 0.05 to 0.06 N·m. For KT4R series,
recommended torque is approximately 0.15 N·m.
• When mounting the KT7 series to the DIN rail, mount it in a
lateral direction. Make sure a click is audible when fixed into
place.
nO
ptional heater burnout alarm output
(for KT7 / KT4H series)
• This alarm output is not available for detecting heater current
under phase control.
• Use the current transformer (CT) provided, and pass one lead
wire of the heater circuit into the hole of CT.
• When wiring, keep CT wire away from power source wire and
load wire to avoid external interference.
• In three phase installations for KT4H series, ensure that R, S
and T are each connected to a 2-line CT that connects with CT1
[⑬ - ⑭] and CT2 [⑭ - ⑮] terminals.

• Terminal screw fastening torque is 0.6 N·m to 1.0 N·m (for KT4R
/ KT8R / KT9R / KT4H / KT4B series). For KT7 series by M3 screw
is less than 0.5 N·m and by M2 screw is less than 0.25 N·m
respectively.
• Use a thermocouple and compensating lead wire according to
the sensor input specification of the controller.
• Use a 3-wire system of RTD according to the sensor input
specification of the controller.
• This controller has no built-in power switch, circuit breaker and
fuse. Therefore, it is necessary to install them in the circuit
near the external controller. (Recommended fuse: Time-lag fuse,
rating voltage 250 V AC, rating current 2 A)
