The TLK38-S is a simplified version of the original TLK38. The new “S” version is identical in size and functionally is similar to the original in many respects, including PID control. However, the list of parameters has been significantly reduced. While this makes the “S” model far easier to program (there’s only one ‘list’ of parameters to scroll through), buyers seeking a replacement for an original TLK38 should check the TLK38-S User Manual to ensure that the “S” model has the functions (parameters) they require.

TLK38 LERR Temperature Controller

TLK38-S is a digital microprocessor-based temperature controller with ON/OFF, Neutral Zone ON/OFF and PID control with an AUTO-TUNING function.

Process values are presented on 4 red LED displays, while the output status is indicated by 2 LED ‘dots’ at the bottom of the display. The instrument is also equipped with 3 LED programmable shift indexes and an LED indication AUTO-TUNING is taking place. Depending on the model, the TLK38-S can have either 1 or 2 outputs: relay type, or that can drive a solid state relays(SSR). We stock the 24V version with two 8-amp SPDT relay outputs TLK38-s LERR.

With two set points available, the TLK38-S 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.

Other available Inputs: 12 VAC/VDC (F type) and 100...240 VAC (H type). Contact us for availability.
