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)

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.
