1.1 - GENERAL DESCRIPTION

TLK 94  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, PID for motorized actuators with

time positioning control. The instrument is equipped with

AUTO-TUNING 

function (FAST or OSCILLATING type),

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

of the event of process disturbances and Set Point variations.

Furthermore, the instrument allows for RS485 serial
communication using MODBUS-RTU communication protocol and
a transmission speed up to 38.400 baud.

 

The process value is

visualized on 4 red displays, the Set value is visualized on 4 green
displays while the outputs status is indicated by 6 leds. The
