1 EN T WIRE - LOOP POWERED AND ISOLATED TRANSMITTER FOR TERMORESISTANCE AND THERMOCOUPLE. GENERAL DESCRIPTION The T instrument converts and transmits the input read into a normalized signal current for..0 ma loop. The signal input may come from thermocouple J, K, R, S, T, B, E, N (EN 6058) sensors or RTD (thermoresistances) like Pt 00 (EN 605), Ni 00 (DIN 60), Pt 500, Pt 000; T besides can read voltages and resistances. The RTD input may be with, or wire connection. GENERAL FEATURES High precision. 6 bit resolution. Isolation 500 Vac. Compact size and fast connection with spring terminals.

4 Configurazione di Fabbrica The instrument is set by the factory with the following configuration (except for other indications on the box): TC wiring Cold junction compensation Input filter Reversed output TC type Measurement Range Start Measurement Full- Scale Output signal in case of fault +, - YES Disable NO K 0 C 000 C Towards the top of the output range. YES: at,5 % over-range values is accetable; at 5% over-range value is considered a fault. Custumized Setting by PC and accessories The configuration by PC use (see the drawing below) is possible with the following accessories: SP: USB to RS/TTL PM00:connection cable between SP and T EASYLP: Dedicated programming software. The module may be programmed even if it is not supplied by the..0 ma loop, since the power supply is provided through the programmer by programming connector. Once the user has at his disposal the above listed accessories, the following parameters may be set : Start and Full scale values of measure. RTD Connection: wires, wires or wires. Measurement filter: Disable. Output: Normal (..0 ma) or reversed (0.. ma). Type input. Cable Resistance Compensation for wires measurement. Output signal in case of fault: t owards the bottom of the output range or towards the top of the output range. Over-Range (*): NO ( the fault alone causes a,5% over-range value) or YES ( a,5% over-range value is accettable a 5 % over-range value is considered a fault). Cold junction compensation : YES/NO ENGLISH- /

Programming connector Electrical connection Input The module allows you to read the thermocouple : J, K, R, S, T, B, E, N and thermoresistance : Pt00 (EN 605), Pt500, Pt000 Ni00 with, or wiring connection; besides T can be used to read voltage (mv) and resistance. The use of shield cables is recommended for the electronic connections -wire connection This connection can be used for short distances ( < 0 m) between module and probe, you should be note that it adds an error (which may be removed by sofware programming) equivalent to the resistance contributed by the connection cables to the measurement. The module must be programmed by PC for wires connection. -wire connection This connection can be used for medium-long distances ( > 0 m ) between module and probe. The instrument performs compensation for the resistance of the connection cables. For a correct compensation the resistance values of each conductors must be the same. The module must be programmed by PC for wires connection. ENGLISH-5/

6 -wire connection This connection can be used for medium-long distances ( > 0 m ) between module and probe. Provides the maximum precision because the instrument measure the resistance of the sensor independently of the resistance of the connection cables. The module must be programmed by PC for wires connection. Potentiometer input A potentiometer with resistence between may be connected directly at module. If the potentiometer has a resistance greater than, K up to 00 K will be necessary to use a resistor in parallel with potentiometer: Ra equals to,5 K RTD wire Connection RTD wire Connection RTD wire Connection TC Connection - + Resistance Connection Potentiometer Connection Voltage (mv) Connection - + Ra =,5 K Output Pot. Current Loop connection (regolated current). The use of shield cables is recommended for the electronic connections. 5 6 Iout RLoad Note: in order to reduce the instrument's dissipation, we recommend guaranteeing a load of > 50 Ω to the curren t output. - U ENGLISH- 6/
