Description
The figure below describes the case of PV input. The remote input and auxiliary analog
input can be set in the same way.
ExampleofTemperatureInput
The figure below is an example of setting Type K thermocouple and a measurement
range of 0.0 to 800.0 ºC.
Minimum value of PV input range
Input type
-270.0°C
1370.0°C
RL = 0.0°C RH = 800.0°C
Maximum value of PV input range
Set a range to be
controlled.

ExampleofVoltageandCurrentInputs
The figure below is an example of setting 2-4 V DC and a scale of 0.0 to 50.0 m³/h.
Minimum value of PV input scale
1 V 5 V (input signal)
SL = 0.0 m³/h SH = 50.0 m³/h
Maximum value of PV input scale
2 V 4 V
RL = 2.000
RL = 1.000
RH = 4.000
RH = 5.000
PV input scale
Input type
Set a range to be
controlled.
PV input range
When using 1-5 V DC signal as is, set RH = 5.000 V, RL = 1.000 V, SDP=1, and SH =
50.0, and SL=0.0.
