TLK38 Temperature Controller
Dual Set-Point Digital Temperature Controller with PID
The STANDARD TLK38 Series has been discontinued and replaced with the "simplified" TLK38-S.
TLK38 Temperature Controller
THE TLK38 SERIES HAS BEEN DISCONTINUED. THE REPLACEMENT IS THE TLK38-"S"
TLK38 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 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 has two (2) relay type outputs.
With two set points available, the TLK38 may be programmed for both (cooling) and reverse action (heating). Great for outdoor electronics enclosures that require both cooling in warm weather and warming in Winter.
Includes NTC Sensor.
