DC Linear Performance
Display Scaling:
Scalable up to –9999 to 10000 for any DC Linear input type.
Minimum Span:
100 display units.
Decimal Point
Display:
Decimal point selectable from 0 to 3 places, but limits to 5 display digits
(e.g. values > 99.9 have no more than 2 decimal places).
DC Input Multi-Point
Linearization: Up to 15 scaling values can be defined anywhere between 0.1 and 100%
of input.
Measurement
Accuracy: 0.1% of span 1LSD.
Maximum Overload: 1A on mA input terminals, 30V on voltage input terminals.
Sensor Break
Protection: Applicable for 4 to 20mA, 1 to 5V and 2 to 10V ranges only.
Break detected within two seconds. Process Control outputs go to the
pre-set power value. Low and Senor Break Alarms operate.
