1 - INSTRUMENT DESCRIPTION
1.1 - GENERAL DESCRIPTION
TLI 40 is a digital microprocessor-based indicator.
The input is programmable and accepts:
Temperature probes
- Thermocouples J,K,S,B,C,E,L,N,R,T
- Thermo-resistances PT100,
- Thermistors PTC and NTC
- Infrared sensors mod. ASCON TECNOLOGIC IRS
Normalized analogue signals
- 0/4..20 mA, 0/1..5 V, 0/2..10 V, 0..50/60 mV, 12..60 mV
Potentiometer
- with resistance > 1 K
Ω
The instrument can have up to 4 alarm outputs : relay type or can
drive solid state relays type (SSR).
One of this output can be analogue type (0/4..20 mA o 0/2..10 V)
and used as measurement retransmission output.
The instrument can be equipped with a programmable digital input
as an alternative to output OUT4.
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, while the output
status is indicated by 4 LED displays.
Other important available functions are: maximum end minimum
peak memory, Hold function, zero calibration (resetting) function
and/or auto-ranging for potentiometer input, programmable
sampling rate (from 8 to 64 sampl./sec.), parameters protection on
different levels.
