■ Linearization Types
Relay rating: 100 V AC @ 1 A (cos ø = 1)
120 V AC @ 1 A (cos ø = 1)
Linear: No linearization
Square root: The input is square root extracted.
User table
240 V AC @ 0.5 A (cos ø = 1)
30 V DC @ 1 A (resistive load)
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 %; -9999 to
+9999 as linearized values
Maximum switching voltage: 250 V AC or 125 V DC
(Limited to the max. voltage 150 V AC or to the use for
Measurement Category I in order to conform with EU

■ Low-end Cutout: Low-end cutout (Low Cut) point
selectable within the range of 0 to 100 %.
With the linear or user table output type,
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.
