1.1 Unit Functions and How They Work
1.1.1 Functions of Unit
Analog input control is available in combination with the CPU unit.
•Temperature data measured by a thermocouple or resistance temperature detector (RTD) is
converted as digital values.
Input with simple programs
•For input data, digital conversion values are read as input devices (WX).
•At the time of the thermocouple input or the RTD input, temperatures are read as integer
values in units of 0.1 degrees.
Ten types of thermocouples and three types of RTDs are supported for each
channel.
•Ten types of thermocouples (K, J, T, N, R, S, B, E, PLII and WRe5-26) and three types of
RTDs (Pt100, JPt100 and Pt1000) can be used. Also, on the thermocouple multi-analog
input unit, they can be used in combination with volotage and current inputs.
•Types of temperature sensors can be changed by the settings of tool software or user
programs.

Various optional settings
Functions to process loaded analog input data are provided. User programs can be simplified.
Function Specifications
Average processing
setting
Averages analog values obtained by sampling and stores them in the I/O area as
digital values. It can be selected from No. of averaging times, time average and
moving average.
Offset/Gain processing
setting Performs the correction of offset values (addition correct) or gain values (magnification correction), and stores the data after processing in the I/O area.
Scale conversion
setting
(Only the voltage and current ranges of the thermocouple mult-analog input unit)
The function makes it possible to convert values to an easy-to-use data range.
Analog input data acquired in a range between preset minimum and maximum values
is scale converted and stored in the I/O area. This function is convenient if used for
scale unit conversion.
Upper/lower limit value
comparison setting
This function compares acquired data with the upper limit and lower limit and turns
ON the upper limit relay or lower limit relay if the acquired data exceeds the upper
limit value or lower limit value.
Max./Min. hold setting
This function maintains the maximum and minimum values of acquired data. Holds
the maximum and minimum digital conversion values when the maximum/minimum
value hold setting is enabled, and stores the values in provided unit memories for
each channel.
Disconnection detection
(Thermocouple multi-analog input unit)
Turns ON the disconnection detection flag when input is disconnected or
unconnected when selecting the thermocouple or the range of 1-5 V 4-20 mA, and
warns of the error state. Also, in case of thermocouple, converts values to digital
values in the range (K30000) which are different from those normally converted.
(RTD input unit)
When the A terminal and b terminal or B terminal and b terminal are disconnected,
converts values to digital values in the range (K30000) which are different from those
normally converted, and warns of the error state.

Tightening the terminal block
•When tightening the terminals of the terminal block, use a screwdriver (Phoenix Contact,
Product No. 1205037) with a blade size of 0.4 x 2.5 (Part No. SZS 0,4x2,5).
•The tightening torque should be 0.22 to 0.25 N·m.
Precautions on wiring
The following precautions should be observed, to avoid broken or disconnected wires.
•When removing the wire's insulation, be careful not to scratch the core wire.
•Do not twist the wires to connect them.
•Do not solder the wires to connect them. The solder may break due to vibration.
•After wiring, make sure stress is not applied to the wire.
•In the terminal block socket construction, if the wire is fastened upon counter-clockwise
rotation of the screw, the connection is faulty. Disconnect the wire, check the terminal hole,
and then re-connect the wire.
