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.
