Output 3 Accuracy:

mA: 0-20mA ± 0.25% of span (20mA) @ 250 ohm

(Recorder Accuracy)

4-20mA ± 0.25% of span (16mA) @ 250 ohm

V: 0-10V ± 0.25% of span (10V) @ 2K ohm
0-5V ± 0.25% of span (5V) @ 2K ohm



Operating Conditions
Ambient Operating Temperature:

0º C to 55º C

Ambient Storage Temperature:

-20º C to 80º C

Relative Humidity:

20% - 95% non-condensing

Supply Voltage:

90 - 264VAC 50/60 Hz (standard)

20 - 50V AC 50/60Hz or 22-65V DC (optional)

Source Resistance:

1000 ohm maximum (thermocouple)

Lead Resistance:

50 ohm per lead maximum balanced (Pt100)



Performance Under Operating Conditions
Temperature Stability:

0.01 % of span/º C change in ambient temperature

Cold Junction Compensation:

Better than ±1º C (thermocouple only)
Note: Thermocouple must not be grounded! Damage to
the cold junction in the control will result!

Supply Voltage Influence:

Negligible

Relative Humidity Influence:

Negligible

Sensor Resistance Influence:

Thermocouple 100 ohm:< 0.1 % of span error
Thermocouple 1000 ohm:< 0.5% of span error
RTD Pt 100 50ohm/lead: < 0.5% of span error

Radiated RF Field Influence:

Degradation of Output 1 accuracy to 3% at
spot frequencies in the range 80-350MHz at field strength of
10V/m.
