1.1 - GENERAL DESCRIPTION

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).

Depending on the model required the input accept:

C

: Thermocouples temperature probes (J,K,S and TECNOLOGIC

IRS Infrared sensors), mV signals (0..50/60 mV, 12..60 mV),

Thermoresistances PT100.

E

 : Thermocouples temperature probes (J,K,S and TECNOLOGIC

IRS Infrared sensors), mV signals (0..50/60 mV, 12..60 mV),

Thermistors PTC and NTC.

I

 : normalized analogue signals 0/4..20 mA

V

 : normalized analogue signals 0..1 V, 0/1..5 V, 0/2..10 V

Other important available functions are: Loop-Break Alarm function,

reaching of the Set Point at controlled speed, ramp and dwell
