Features

The KT4H uses our time-proven display system (negative type LCD + LED backlight) that is used in our timers and counters.
11-segment LCD makes letters easy to distinguish.
Largest PV indication in its class for easy readability even from a distance.
Also PV value can be switched among 3 colors so process status can be easily determined.

1.Better visibility

1.With negative type LCD and backlight, values can be read even under direct sunlight. Also, 11-segment LCD improves ability to distinguish alphanumerics.

2.Letter height of PV value has been enlarged to 12 mm/ .472 inch enabling it to be directly read even from a distance.

3.Ability of PV value to change into three different colors allows process status to be determined at a glance.

2.Improved control functions

Capable of 4-point temperature selection by external input.

Control output can be turned ON and OFF externally.

3-phase heater burn-out detection function

Non-contact voltage output in heating/cooling control output available.

• 1.Four setting value (SV) selectable using external input. (option)
• 2.External ON and OFF switching of control output possible (option)
• 3.Heater burn-out alarm supports 3-phase heaters (option)
• 4.Supports voltage output for heating/cooling control (for SSR drive) (option)

3.Improved communication functions

1.Connect via Ethernet using our DLU (Web Datalogger Unit).

MEWTOCOL communications protocol is built in. Up to 31 units can be connected and data can be collected using a DLU or similar.

2.External tool port comes standard

Using the external tool port, all settings can be loaded and settings can be made.

4.Space savings

Control panel installation length has been shortened to the utmost.

5.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).

6.High accuracy and high sampling period also inherited from KT Series

The operation mode uses "PID control" which allows a stable temperature to be maintained. Capable of high accuracy with an input span of °C0.2% and a high-speed sampling period of 250 ms.

7.Easier operation

The switch layout has been changed and mode changes easier using the front keys.
Improved switch construction provides a much more positive clicking action.

8.Protective construction

Despite its compact size, protective structure conforms to IP66 (front panel only, when using rubber packing).
