Valve controller

Name: Valve controller
SKU: Ascon KX6
Availability: InStock

Process Controller

Model : Ascon KX6

Brand: Ascon Tecnologic

The controller that learns everything by itself!

Designed for valve control … but not only.

Dimension: 48 × 96 mm
Control function: PID single action (direct or reverse)for servomotor control or linear output (mA/V), PID Heating, or Heating/cooling action. On/Off, On/Off with Neutral Zone, Autotune, Selftune, and evoTune.Overshoot control and 4 selectable set points.
Alarm function: Two alarms programmable as absolute, deviation, band
Serial communication: TTL (standard) + RS485 (optional), Modbus RTU protocol with 1200… 38400 baud rate.
evoGreen: Stand-by mode of display for energy saving
evoTune: the best tunning solution for the current situation and “trouble-free” adjustment.
Automatic Learning: potentiometer, servo motor stroke time

Alarm function

KX6 has the capability to generate various types of alarms based on the process requirements.

- Absolute low alarm (LoAb)
- Absolute high alarm (HiAb)

Absolute band alarm with alarm indication out of the band
Absolute band alarm with alarm indication inside the band
Sensor break
Deviation low alarm (relative)
Deviation high alarm (relative)
Relative band alarm with alarm indication out of the band
Relative band alarm with alarm indication inside the band

Control function

The device can be programmed for 2 control types:

- Two control actions (heat & cool) with 2 methods:
- PID (heat and cool);
- Heat/Cool ON/OFF control with neutral zone;

and

- One control action (heat or cool) with 4 methods:
- PID (heat or cool);
- ON/OFF asymmetric hysteresis;
- ON/OFF symmetric hysteresis;
- Servomotor control (available when Output 2 and Output 3 have been ordered as “M”)

KX6 also has the Fuzzy overshoot control feature that reduces the overshoot usually present at instrument start-up or after a set point change, and by setting a value between 0.00 and 1.00, it is possible to slow down the instrument action during the set point approach.

Automatic Potentiometer Calibration

KX6 Valve controller can also automatically calibrate a standard potentiometer with two digital output signals. This functionality will ensure an accurate and stable valve control solution.
