)
•
Input type: Universal input system. The input type can be selected with the software.
•
Sampling period: Can be selected from 100, 200 and 500 ms.
•
Burnout detection: Functions at TC, RTD, standard signal (0.4 to 2 V or 1 to 5 V)
Upscale, downscale, and off can be specified.
For standard signal, burnout is determined to have occurred if it is 0.1 V or less.

•
Measurement current (RTD): About 0.13 mA
•
Input resistance: 1 M
or more for thermocouple or mV input
About 1 M
for DC voltage input
•
Allowable signal source resistance: 250
or less for thermocouple or mV input
Effects of signal source resistance: 0.1

•
Applicable standards: JIS, IEC, DIN (ITS-90) for thermocouples and RTD
Auxiliary Analog Input Signals
Available only for controllers with auxiliary analog input terminals.
These signals are not used in single-loop control, however.

•
Input type: Settable in a range of 0-2, 0-10, 0.4-2.0, or 1-5 V DC
•
Sampling period: 100, 200 and 500 ms
The sampling period of a remote input signal is associated with the PV input’s sam-
pling period.
