LINEARIZATION

Linearization Types
Linear
: Proportional to the input
Square root: The input is square root extracted.
User's table: Segment linearization
Calibration points: Max. 128 points; the input % and linearized value in scaling are specified in pairs.
Selectable range: -7.5 to +107.5 % as input %; -99999 to +999999 as linearized values
Low-end Cutout:Low-end cutout (Low Cut) point selectable within the range of 0 to 100 %.
With linear or segment linearization,
the output signal is forcibly set to 0 % for the input lower than the low-cut point. With the square root extraction, the output signal is linear to the input when the latter is lower than the low-cut point.

INSTALLATION

Power Consumption
AC:
 ≤ 7 VA at 100 V
 ≤ 10 VA at 200 V
 ≤ 12 VA at 264 V

PERFORMANCE

Accuracy (display accuracy, setting accuracy): differs depending on the linearization type.
Linear: ±(0.08 % of FS + 1 digit)
Square root extraction (1 % or more of input): ±(0.15 % of FS + 1 digit)
Segment linearization: 
  ±(0.08 % of FS + 1 digit) [gain ≤ 1]
  ±(0.08 % x gain of FS + 1 digit) [gain > 1]
See CALCULATION EXAMPLES OF OVERALL ACCURACY.
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F)
Response time (Filter time constant: 0 sec.): ≤ 0.5 sec.
(0 – 100 % at 90 % setpoint)
Line voltage effect: ±0.1 % over voltage range
Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength: 2000 V AC @ 1 minute (input to L1 or L4 alarm output to L2 or L3 alarm output to power to ground)
(for output code 5, L3 alarm output and L4 alarm output is not available)

CALCULATION EXAMPLES OF OVERALL ACCURACY

[Example] Input Range: 0 – 20 mA, Input Setting: 4 – 20 mA (when the linearization type is linear)
• Accuracy = Input Range Span (20 mA) ÷ Input Span Setting (16 mA) × 0.08 % = ±0.1 % + 1 digit
