1.1 - GENERAL DESCRIPTION
TLK 33 is a single-loop digital microprocessor-based controller for
PELTIER ELEMENTS with 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.
for its
The instrument has an output with automatic reverse polarity for the
therefore
direct command of PELTIER devices at 12 to 24 Volts DC, a
maximum current absorption of 7 Amps and can also have up to 2
alarm outputs to pilot static relays (SSR).
Ascon
Furthermore, the instrument allows for 2 digital inputs and 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, while the output
status is indicated by 4 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 4 outputs: relay type or can drive solid state relays type
(SSR).
Depending on the model required the input accept:
D: Thermoresistances PT100, Thermocouples temperature probes
(J,K,S and ZIS Infrared sensors), mV signals (0..50/60 mV, 12..60
mV),
