In addition to input module and output module, there is also a module with both input circuit and output circuit. The input and output points are generally the same. This module makes it more convenient for users to determine the hardware configuration of PLC.
The rated value of the output current is related to the nature of the load. For example, the relay output module of FX can drive the resistive load of 2A/220VAC, but only the inductive load of 80VA/220VAC and the incandescent lamp of 100W. The rated output current is also related to temperature. When the temperature rises, the rated output current decreases. Some PLCs provide relevant curves.
Due to heat dissipation, some output modules need to consider the total current of several output points belonging to the same common point (COM). For example, the rated output current of the transistor output module of FX is 0.8A/COM.
The use voltage of the relay output module is * * *, the conduction voltage drop is small, and the ability to withstand transient overvoltage and overcurrent is strong, but the action speed is slow, and the service life (action times) is limited. If the on-off change of load is not very frequent, it is recommended to choose relay type first.
Transistor type and bidirectional thyristor type modules are used for DC load and AC load respectively. They have high reliability, fast response speed and long service life, but their overload capacity is slightly poor.
The AI830/AI830A RTD input module has eight channels for measuring temperature through a resistive element (RTD). With 3-wire connection. All RTDs must be isolated from the ground.
AI830/AI830A can be used with Pt100, Cu10, Ni100, Ni120 or resistance sensors. Perform linearization and temperature to Celsius or Fahrenheit conversion on the module.
Each channel can be configured separately. The MainsFreq parameter is used to set the power filter cycle time. This will provide a notch filter at (50 Hz or 60 Hz)
