FEATURES
1. Multi-input
Versatile thermocouple, RTD, DC voltage
and DC current input for temperature
detecting sensors
2. 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%.
3. DIN Rail mounting types are aligned
taking global market demand into
consideration
The KT7 series is equipped with DIN rail
mounting complying to DIN standards.
Furthermore, because its control panel is
compact, the KT7 saves space.
2009.10
4. Nine step pattern control possible.
For KT2 series, despite DIN 48 × 24 size,
selection is possible of control with fixed
set point and nine step pattern control.
5. Meets market demands for costeffectiveness
The KT series offers both economy and
high performance.
6. The KT series complies with UL,
CSA standards and CE marking.
7. Improved visibility and ease of
operation
More compact than before
The KT4H/KT4B series features the
largest PV digit size in the industry.
Visibility is improved with an 11-segment
display. Connectable to a PC, it offers a
full range of control and communication
functions.

8. Communication specification uses
RS485 (Modbus protocol)
(Sample System Configuration)
FPΣ Programmable Controller
(Panasonic Electric Works)
RS-485
Up to 31 units can be connected
* In the configuration above, the FPΣ requires a
communication cassette (FPG-COM3).
* Modbus is a communication protocol developed for
PLCs by Modicon Inc.

KT (AKT2,4,7,8,9,4H,4B)
INSTALLATION
1. KT2 series
Please install vertically in order to satisfy the IP66 specification for dust and splash proofing.
The possible control panel plate thickness for installation is between 1 to 10 mm.
(1) Insert the unit from the front of the control panel.
(2) Insert the mounting frame until that the edges (2) make contact with the panel.
(3) Tighten the clamp screw and then turn it 3/4 of a turn after the edge of the screw reaches the panel.
2. KT4, 7, 8, 9 series
• Panel Mounting
Mountable panel thickness: Within 1 to 15mm .039 to .591inch
Insert a controller from the front side of the panel.
Attach the mounting brackets by the holes at the top and bottom
of the case and secure the controller in place with the screws.
• DIN rail mounting (KT7)
1) Hook 1 of the KT7 on the upper side of the DIN rail.
2) Making the 1 part of the KT7 as a support, fit the lower part
of the KT7 to the DIN rail.
KT7 will be completely fixed to the DIN rail with a “Click” sound.
Recommended DIN rail: Part No. ATA48011
Recommended fastening plate: Part No. ATA4806

Notice
As the case is made of resin, do not
use excessive force while screwing
in the mounting bracket. The torque
is approximately 0.12N·m
3. KT4H/4B series
Please install vertically in order to satisfy
the IP66 specification for dust and splash
proofing.
The possible control panel plate
thickness for installation is between 1 to 5
mm.
1) Insert the unit from the front of the
control panel.
2) Push the installation frame fully into
contact with the panel and tighten the
screws (screw torque from 0.05 N·m to
0.06N·m).

Notes: 1. Terminating Resistors (Terminators)
The KT series has a built-in pull-up resistor or pull-down resistor, which
serves as the terminating resistor. For this reason, do not connect the
terminating resistor on the communication line.

Please use a cable that is suitable for a modular connector.

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

The KT4H series has a built-in pull-up resistor or pull-down resistor. For this reason, do not connect the
terminating resistor on the communication line.

NOTICE ON OPERATION
1. NOTICE ON SITE SELECTION
This instrument is intended to be used in
the following environment (IEC61010-1)
Overvoltage category II, Pollution degree
2
Mount the controller in a place with:
1) A minimum of dust, and an absence of
corrosive gases
2) No flammable, explosive gases
3) Few mechanical vibrations or shocks
4) No exposure to direct sunlight, an
ambient temperature of 0 to 50°C (32 to
122°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.)
5) Locations in which temperature rapidly
changes may cause condensation.
6) Locations or atmospheres in which
gasoline, thinners, alcohol, or other
organic solvents are present, or in which
ammonia, sodium hydroxide, or other
strong alkaline substances may adhere.
7) Locations susceptible to direct impact
or the transmission of vibrations, or
where splashing with water is possible.
8) 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.
9) An ambient non-condensing humidity
of 35 to 85%RH
10) No large capacity electromagnetic
switches or cables through which large
current is flowing
11) No water, oil or chemicals or where
the vapors of these substances can come
into direct contact with the controller
2. NOTICE ON THE WIRING
1) The terminal block of KT4, 8, 9, 4H, 4B
series are designed to be wired from the
left side (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 solderless
terminal with insulation sleeve that fits to
the M3 screw.

2) Terminal fastening torque is approximately 0.6N·m to 1.0N·m (KT4, 8, 9, 4H
and 4B).
For KT7 series by M3.0 screw is less
than 0.5N·m and by M2.0 screw 0.25N·m
respectively.
3) Use a thermocouple and
compensating lead wire according to the
input specification of the controller.
4) Use a 3-wire system of RTD according
to the input specification of the controller.
5) This controller has no built-in power
switch, circuit breaker or fuse. Therefore,
it is necessary to install them in the circuit
near the external controller.
(Recommended fuse: Time-lag fuse,
rated voltage 250V AC, rated current 2A)
6) In the case of 24V AC/DC power
supply, do not confuse the polarity when
it is DC.
7) With the relay contact output type, use
an auxiliary electromagnetic switch
externally according to the capacity of the
load to protect the built-in relay contact.
8) When wiring, keep input wire
(thermocouple, RTD, etc.) away from AC
source and load wire to avoid external
interference.
9) Turn 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.

10) Do not drop wire chips into the holes
of vent when wiring, because they could
cause fire, malfunction or trouble with the
device.
11) To prevent the unit from harmful
effects of unexpected high level noise, it
is recommended that a surge absorber
be installed between the electromagnetic
switch coils.
3. NOTICE ON THE MOUNTING
1) Do not use excessive force while
screwing in the mounting bracket of KT4,
8, 9, 4H and 4B series. For KT4, 8 and 9
series, recommended torque is approximately 0.12N·m. For KT4H and 4B,
recommended torque is approximately
0.05 to 0.06 N·m.
2) 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.
4. OPTIONAL HEATER BURN-OUT
ALARM OUTPUT (KT4, 7, 8, 9, 4H and
4B series)
1) This alarm is not available for detecting
current under phase control.
2) Use the current transformer (CT)
provided, and pass one lead wire of the
heater circuit into the hole of CT.
3) When wiring, keep CT wire away from
AC source and load wire to avoid external
interference.
4) In three phase installations, 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.

5. Please use rod terminals for the
terminal portion of the KT7 series.
We recommend terminals made by
Phoenix Contact.
(1) to (4) are AI0.25–8YE, AI0.34–8TQ,
AI0.5–8WH, AI0.75–8GY, AI1.0–8RD,
and AI1.5–8BK.
(5) to (9) are AI0.25–8YE, AI0.34–8TQ,

The screw tightening torque for (1) to (4)
should be no more than 0.5 N·m and for
(5) to (9) it should be no more than 0.25
N·m. Make sure no screw is loose.
