LK3U PLC

LK3U PLC

The LK3U series PLC Controller is a China-based programmable logic controller that is compatible with the Mitsubishi FX3U series. This means it supports the same programming software, GX-Developer 8.5, and has the same capabilities as the FX3U. Including a PID (proportional-integral-derivative) function in the LK3U series PLC is a common feature in modern PLCs. It is used for control applications, such as temperature control, flow control, and pressure control. It allows the PLC to continuously adjust its control output based on the feedback from the process being controlled.

LK3U series PLC Controller Specifications

  1. The input signal is a DC24V NPN type with a minimum drive current of 10mA.
  2. The MR model has a relay output mode with a maximum drive voltage of AC250V/DC30V and a maximum drive current of 3A, with a peak value of 5A. The MT model has a transistor output mode with a signal type of DC24V NPN (active low) and a maximum drive current of 500mA.
  3. The analog input type is default 0-10V but can be changed to 0-20mA input or NTC thermistor input.
  4. The analog output type is 0-10V.
  5. The high-speed X0-X1 input has a frequency of 60KHz.
  6. The MT series has 8 high-speed outputs (Y0-Y7) with a frequency of 80KHz.
  7. The dimensions do not include terminals.
  8. The CAN communication port is only used for internal networking between the company's PLCs.

This information helps us understand the capabilities and limitations of the LK3U series PLC and can be useful in determining whether it is suitable for a particular application.

The output is compatible, connected to G- V+ is 0-10V output, G- I+ is 0-20ma output
