Your Simple, Accurate and Economical

Temperature Controller

Compact temperature controller (DIN

48×24) that can support pattern control

Additions to KT2 series

Broad lineup of temperature controllers

allow you to satisfy application and space requirements.

Compliance with RoHS Directive

(Sample System Configuration)

FPΣ Programmable Controller

(Panasonic Electric Works)

Up to 31 units can be connected

RS-485

*In the configuration above, the FPΣ requires a

communication cassette (FPG-COM3).

*Modbus is a communication protocol developed for

PLCs by Modicon Inc.

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.

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 cost-

effectiveness

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)

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.

KT (AKT2,4,7,8,9,4H,4B) 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.
