The input module is the most used module in the control system RJ71C24-R4 PDF.
According to the input voltage, the input points of different, choose the most suitable user needs of the module RJ71C24-R4
1 modules are equipped with a variety of functions.
Can be through a single input module to 1 points for the unit to set the high speed response, interrupt input function.
In addition, the public end of the module can be freely selected as the common end of the positive pole and the negative pole RJ71C24-R4 PDF.
It is not necessary to use different modules according to the input specifications and functions, and reduce the number of modules,
Therefore slot occupied quantity can be reduced by 20% than in the past, the deployment cost can be reduced by 60% compared with the previous. Analog input channel number: 16CH.

Execute event driven program through alarm output
Strengthen the implementation of the interrupt function according to the alarm output flag, easy to carry out preventive maintenance.
The measured value and the change rate of the analog input signal exceed the upper and lower limits of the set,
Regardless of the procedure of the scan time, can be executed interrupt handling, quickly respond to abnormal conditions.
Analog input module for the external analog signal into the interface of the programmable controller.
Can choose the channel between the insulation, voltage input, current input, voltage / current mixed input, thermocouple input, temperature rresistance (RTD) input for a variety of purposes, such as modules RJ71C24-R4 datasheet.
Filter high frequency interference.
Analog input module has been equipped with a first order lag filter.
The analog input signal with high frequency interferencee component can be obtained by using the first order lag filter RJ71C24-R4 datasheet.
Parameters can be set through the filter time constant, no program can be easy to use.
