14.1 Input Section Specifications
Common to Control and Measurement
Thermocouple burnout: Detection ON/OFF switchable (on each channel)
Burnout up scale/down scale switchable
A/D integral time: Select from 20 ms (50 Hz), 16.7 ms (60 Hz), 100 ms (50/60
Hz), and AUTO (automatically switches between 20 ms and
16.7 ms from the power supply frequency)
Control Input
Number of inputs: Up to 10 inputs (depends on the model and control mode)
Period: 250, 500, 1000 ms (synchronized with the control period, 1000
ms when the A/D integral time is set to 100 ms)
Input type: DCV (DC voltage), TC (thermocouple), RTD (resistance
temperature detector), DCA (DC current, by adding an external
shunt resistor)
Linear scaling: Input ranges capable of scaling: TC, RTD, DCA
Available range of scaling: –30000 to 30000 and the span within 30000
Decimal point position:
Can be set arbitrarily
Unit: Can be set arbitrarily using up to 6 characters
Standard signal burnout: For control input, burnout detection is possible not only on
thermocouples but also standard signals.
PV input computation: Input processing, square root computation (low cut 0.0 to 5.0%), ten-
segment linearizer approximation, ten-segment linearizer bias, bias
addition (in the measurement span of –100.0 to 100.0%), first-order
lag computation (time constant from 1 to 120 s, off)
Auxiliary input computation: Input processing, square root computation (low cut 0.0 to
5.0%), bias addition (in the measurement span of –100.0 to
100.0%), ratio computation (0.001 to 9.999), first-order lag
computation (time constant from 1 to 120 s, off)
