Performance
Reference Conditions
Ambient Temperature:
20ºC ± 2ºC
Relative Humidity:
60-70%
Supply Voltage:
90-264V AC 50Hz ±l %
Source Resistance:
<10 ohm for T/C input
Lead Resistance:
<0.1 ohm/lead balanced (Pt100)
Performance Under Reference Conditions
Common Mode Rejection: >120dB at 50/60Hz giving negligible effect at up to
264V 50/60Hz
Series Mode Rejection: >500% of span (at 50/60Hz) causes negligible effect
DC Linear Inputs
Measurement Accuracy: ± 0.25% of span ± 1 LSD
Thermocouple Inputs
Measurement Accuracy: ± 0.25% of span ± 1 LSD
(Note: Reduced performance with Type B T/C between 100-600ºC
(212 - 1112ºF)
Note: Thermocouple must not be grounded! Damage to the
cold junction in the control will result!
Linearization Accuracy:
Better than ± 0.20C any point, any 0.1ºC range (±
0.05ºC typical). Better than ± 0.50C any point, any 1ºC range.
Cold Junction Comp:
Better than ± 0.7ºC
RTD Inputs
Measurement Accuracy: ± 0.25% of span ± 1 LSD
Linearization Accuracy:
Better than ± 0.2ºC any point, any 0.1ºC range
(± 0.05ºC typical). Better than ± 0.5ºC any point, any 1ºC range.
