1.1 - GENERAL DESCRIPTION
TLK 48 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 3 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 3 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
