Compliance with RoHS Directive

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)

(Sample System Configuration)

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.
