Main features

The current status is obvious at a glance (Large display + 3-stage display)

Various information is displayed on the large LCD.

At-a-glance monitoring of the controller.

Use of direct keys simplifies the operation

Frequently used keys are assigned to the direct keys. This avoids operator’s operation errors and thus realizes easy-to-understand key operations.

The controller adjusts setting according to the equipment to be controlled. (Level-PID automatic setting)

Level-PID function is widely used on Ramp/Soak controllers.

Level setting of each level is automatically calculated by the controller.

Without advanced knowledge, the initial setup will be automatically completed by the controller.

Front loader communication port

All models are equipped with a front loader communication port for improved maintainability Configuration data management software (PROTEM2) is available

This model can be used in advanced applications that were only handled by upper models

16 segments by 16 pattern The pattern link function allows setting up to 256 segments.

Up to four time signal outputs can be provided in one pattern. The use of logic operation allows setting up to 4 points per DO to handle complicated external sequences.
