sante inquinamento ambientale: normale
Isolamenti:
Le parti in “Bassa” tensione presentano un isolamento
principale rispetto alle parti in bassissima tensione. Fra le
parti in bassissima tensione e il frontale esiste un isola-
mento supplementare. I particolari in bassissima tensione
(ingresso sonde, ingresso digitale e uscite 10 Vdc per
SSR - relè a stato solido, collegamento seriale e alimenta-
zione*), non presentano alcun isolamento.
*Nota: per l’alimentazione sono esclusi i modelli IRDRV,
IRDRW e IR32*H, che presentano un isolamento principale.
Uscite:
Numero relè (a seconda del modello):
IR32 per NTC: 1, 2 o 4 relè SPDT altri IR32V: 1 relè SPST
IR32W: 1 relè SPST + 1 SPDT
IR32Z: 1 relè SPST + 3 SPDT
IRDRTE, IRDRV e W: 1 o 2 relè SPDT
IRDRZ: 1° e 2° relè SPDT, 3° e 4° relè SPST
Uscite per SSR (Relè stato solido)
Numero uscite (a seconda del modello):
IR32D: 1
IR32A e IRDRA: 4

current 4/20mA or 0/20mA
voltage -0,4/+1Vdc
Operating range:
NTC: -50/90 °C;
Pt100: -100/600 °C,
ThcK: -100/999 °C;
ThcJ: -100/800 °C
current/voltage: -99/999
Resolution:

1 in the remaining field
Accuracy:
±0.5% of the full scale
Power supply:
voltage:
IR32V,D,W,Z,A: from 12 to 24Vac-dc ±10%
IR32V*H: from 110 to 240Vac-dc ±10%
IRDR V & W: 24Vac ±10% and 220/240Vac ±10%
IRDRTE: 220/240Vac ±10%
IRDRZ, IRDRA: from 12 to 24Vac-dc, ±10%
power consumption:
IR32D, IR32V: 2VA;
IR32A, IR32W, IR32Z and IR32V*H: 3VA
IRDRA, IRDRTE, IRDRV, IRDRW: 3VA
IRDRZ: 4VA
sensor power supply output:
10Vdc, max 30mA (8Vdc for IRDRW)
Operating conditions:
working temperature: 0T50°C
storage temperature: -10T70°C
ambient relative humidity: lower than 90%rH, not condensing
ambient pollution: normal
Insulation:
low voltage sections have a main insulation in comparison
with the very low voltage ones.
There is extra insulation between very low voltage sec-
tions and the front panel of the instrument. Very low volta-
ge components (sensor inputs, digital input, 10Vdc out-
puts for SSR, serial connection and power supply*) do not
have any insulation.
*Important: except models IRDRV, IRDRW and IR32*H,
complete with main insulation.
Outputs:
Number of relays (depending on the model):
IR32 for NTC: 1, 2 or 4 SPDT relays, other IR32V: 1 SPST relay;
IR32W: 1 SPST relay + 1 SPDT;
IR32Z: 1 SPST relay + 3 SPDT;
IRDRTE, IRDRV & W: 1 or 2 SPDT relays
IRDRZ: 1st & 2nd relay SPDT, 3rd & 4th SPST
