1.1 - GENERAL DESCRIPTION
TLK 94-A is a "single loop" digital microprocessor-based controller,
for its
with ON/OFF, Neutral Zone ON/OFF, PID single action, PID dual
action (direct and reverse) control and with AUTO-TUNING
function (FAST or OSCILLATING type), and automatic calculation
of the FUZZY OVERSHOOT CONTROL parameter for PID control.
Ascon
of
The PID control has a particular algorithm with TWO DEGREES
OF FREEDOM
independently in the event of process disturbance and Set Point
variations.
The process value is visualized on 4 red display, the Set value is
visualized on 4 green display while the outputs state is indicated by
6 led.
The instrument can have up to 5 outputs: relay type or to drive solid
state relays type (SSR).
The input is programmable and accepts temperature probes
(Thermocouples J,K,S,B,C,E,L,N,R,T; Thermo-resistances Pt100,
Pt1000; Thermistors PTC and NTC; Infrared sensors mod.
TECNOLOGIC IRS) and normalized analogue signals (0/4..20 mA,
0/1..5 V, 0/2..10 V, 0..50/60 mV, 12..60 mV).
The instrument can be equipped with an input for the current
transformer, working as a Heater Break Alarm function
that optimises the instrument's features
