2) 11-segment LCD improves ability to
distinguish alphanumeric.
3) Largest letter height of PV value in its
class for easy readability even from a
distance.
2. Space savings (Depth: 56mm)
Control panel installation length has been
shortened to the utmost.
3. Ability to use any sensor (input) is
inherited from KT Series
The KT4H comes standard with ability to
use any sensor (input): thermocouple
(10 types), RTD (2 types), DC current
(2 types), and DC voltage (4 types)
4. Simple operation enables highly
accurate temperature control
The operation mode uses “PID control”
which allows a stable temperature to be
maintained. Capable of high accuracy
with an input span of ±0.2% and a highspeed sampling period of 250 ms.
5. Improved communication functions
1) MEWTOCOL communications protocol
is built in. Up to 31 temperature

can be collected using a DLU (Web
KT4H Temperature
Controller
Datalogger Unit) or similar.
2) Using the external tool port, all settings
can be loaded and settings can be made.
6. Easier operation
1) The switch layout has been changed
and mode changes easier using the front
keys.
2) Improved switch construction provides
a much more positive clicking action.
7. Protective construction
Despite its compact size, protective
structure conforms to IP66 (front panel
only, when using rubber packing).
8. Improved control functions (option)
1) Capable of 4-point temperature
selection by external input.
2) Control output can be turned ON and
OFF externally.

conditions of use. This is known as specification setting.
Factory settings at time of shipment are, input: K -200° to 1,370°C; and
Alarm 1: no operation, comes into operation reverse (heating). If the
factory settings are acceptable, the specification settings will be
appropriate when the device is installed into the equipment and the
specification setting procedure will not be required
3. Basic setting operations
For setting-mode navigation, refer to the particular setting mode.
After navigation using the and keys, setting (selection) of each
setting (selection) item is done by registration using the key.

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.)
2. Terminating Resistors (Terminators)
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.

INSTALLATION
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).
NOTICE ON OPERATION
1. Notice on site selection
This instrument is intended to be used in the following
environment (IEC61010-1)
Over voltage 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 KT4H series is designed to be wired
from the left side
The lead wire must be inserted from the left side of the terminal,
and fastened by the terminal screw. Use a solder-less terminal
with insulation sleeve that fits to the M3 screw.

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
Do not use excessive force while screwing in the mounting frame
of KT4H series. Recommended torque is approximately 0.05 to
0.06 N⋅m.
4. OPTIONAL HEATER BURN-OUT ALARM OUTPUT
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.
CT input terminal
Power supply

2) Recommended terminal fastening torque is approximately:
0.6N⋅m to 1.0N⋅m.
3) Use a thermocouple and compensating lead wire according to
the input specification of the controller.

Shieldedwire
Connectonly oneside ofthe shieldedwiretotheFG terminalso that currentcannot
flowto the shielded wire.If bothsides of the shieldedwireare connected to theFG
terminal, the circuit will be closedbetween the shielded wire and the ground. As a
result, current willrun throughthe shieldedwire and this maycause noise.Be sure
togroundtheFG terminal.
Terminator(Terminalresistor)
Do not connect terminator with the communicationline because eachKT4H/B has
built-inpull-upand pull-downresistorsinstead of a terminator.
If there is a large distance between the PLC and the KT4H/B, connect the
terminator on thePLC side.(Connecta terminatorof120 or more resistance.)

RS-485 communication timing
Master side (Notice on programming)
Set the program so that the master can disconnect the transmitter from the
communication line within a 1character transmissionperiod after sending the
command in preparation for reception of the response from the slave.
To avoid the collision of transmissions between the master and the slave, send
thenextcommandaftercarefullycheckingthatthe masterreceivedtheresponse.
Slave side
When the slave starts transmission through the communication line, the slave
is arrangedso asto provide an idle status(mark status)transmission period of
5ms or more (communication response time from 5 to 99ms settable) before
sending the response toensure the synchronization on thereceiving side.
Theslaveis arrangedso as to disconnectthe transmitter fromthe communication
line withina 1 character transmission period after sendingthe response.
• Response with data
When the master sends the reading command, the
slave responds with the corresponding set value or
current status.
• Acknowledgement
When the master sends the setting command, the
slave responds by sending the acknowledgement
after the processing is terminated.
• Negative acknowledgement
When the master sends non-existent command or
value out of the setting range, the slave returns the
negative acknowledgement.
• No response
Theslavewill notrespondtothemasterinthefollowing cases.
• Global address “FF”(MEWTOCOL)is set.
• Broadcast address (Modbus protocol) isset.
• Communication error (framing error, parity error)
