TLK38 Controller with programmable input

New product
 
More info

TLK 38 is a “single loop” digital microprocessor-based controller, with ON/OFF, Neutral Zone ON/OFF, PID single action, PID dual action (direct and reverse) control and with AUTO-TUNING FAST function, SELF-TUNING function and automatic calculation of the FUZZY OVERSHOOT CONTROL parameter for PID control. The PID control has a particular algorithm with TWO DEGREES OF FREEDOM that optimises the instrument’s features independently in the event of process disturbance and Set Point variations. The process value is visualized on 4 red displays, while the output status is indicated by 2 LED displays. The instrument is equipped with a 3 LED programmable shift indexes. The instrument provides for the storage of 4 Set Points and can have up to 2 outputs: relay type or can drive solid state relays type (SSR).

Features

  • 78x35 mm panel mount controller with single display
  • 1 probe input
  • up to 2 relay outputs
