With twice the responsiveness, it for items such as frequently used and frequently changed settings. is possible to more finely carry out control, for example, of the heat Smooth operation is enabled at initial startup and after changing capacity. settings. Built-in easy programming function Built-in rearing auto tuning function Easy programmed control made possible using nine-step setting The built-in rearing auto tuning function uses the step response procedure. By entering specific target values for each indicated period, method. From temperature rise behavior alone, it can calculate the PID freely selectable temperature control is possible. constants. It is possible to calculate constants, even when auto tuning cannot be used to generate them. Example: From start of programmed control Because an ON / OFF operation is unnecessary, there is no disruption in control. Perform control so it becomes 200 C 392 F after 1 hour. Maintain 200 C 392 F until after 2 hours Step 1 2 3 4 5 Temperature Perform control so it becomes 300 C 572 F after 30 minutes.

Unit 60 mm 2.362 in approx. long: compact design saves space. With DC current output, can be used as simple signal converter. 0 C 32 F Shared features of KT series Improved visibility and ease of operation Multi-input sensors More compact than before Versatile thermocouple, RTD, DC voltage and DC current input for temperature detecting sensors The KT4H / KT4B series features improved visibility with a process value (PV) character height of 12 mm 0.472 in and an 11-segment display. Connectable to a PC, it offers a full range of control and Simple operation enables highly accurate temperature control communication functions. All required operations can be enabled by the front keys and highly accurate PID control mode ensures an input span of 0.2 %. Communication specification uses RS485 (Modbus protocol) (Sample System Conguration) DIN Rail mounting types are aligned taking global FP Programmable Controller market demand into consideration (for KT7 series) The KT7 series is equipped with DIN rail mounting complying to DIN standards. Furthermore, because its control panel is compact, the KT7 series saves space. RS485 Nine step pattern control possible. (for KT2 series) For KT2 series, despite DIN 48 x 24 size, selection is possible of control with fixed set point and nine step pattern control. Meets market demands for cost-effectiveness The KT series offers both economy and high performance. Up to 31 units can be connected The KT series complies with UL/c-UL standard and CE marking. *1 Only on type equipped with communications function. *2 In the configuration above, the FP requires a communication cassette (FPG-COM3). *3 Modbus protocol is a communication protocol developed for PLCs by Modicon Inc. 2
