Main features

High Speed Sampling Time 10msec.

Feedback control with 100 samplings per second enables controlling a fast changing process that was difficult to control. Such applications include pressure, flow rate, and pulse heat.

Front loader communication port

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

Large high intensity LCD display

Large easy-to-read PV display on a compact front panel

2 inputs for various applications

2CH (Dual loop) control
Dual loop control is available on a single controller.

PV select function
Input 1 and Input 2 are switched over at a preset level.

Differential temperature control
This is a function to control to maintain the difference between PV1 and PV2 is kept constant.

Further advanced control performance and function

Proactive function is supplied to suppress overshoot and bottom (lowering amount)

Versatile customizable information display

Three-stage display shows abundant information.

Parameter select function enables displaying necessary parameters only.
