INSTRUMENT ORDERING CODE
1 - INSTRUMENT DESCRIPTION
1.1 - GENERAL DESCRIPTION
TLK 72 B is a digital microprocessor-based controller, with ON/OFF,
Neutral Zone ON/OFF, PID single action, PID dual action (direct
and reverse) control and with
AUTOTUNING
function (FAST or
OSCILLATING type).
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 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 Ascon
Tecnologic ZIS Infrared sensors), mV signals (0... 50/60 mV, 12...
60 mV), Thermoresistances PT100.
E
: Thermocouples temperature probes (J, K, S and Ascon
Tecnologic ZIS 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
