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)
FP
Σ
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.
