LK3U-14MR/MT-4AD-2DA 8 Input 6 Output Plc Controller Rs485 Rtc
LK3U-14MR4AD-2DA has 8 DC24V NPN input channels and 6 output channels, which can be either a relay or transistor type depending on the model chosen (MR for relay and MT for transistor). The maximum load that can be switched by the relay outputs is AC250V/DC0V-DC30V at less than 3A, while the transistor outputs can switch DC24V at less than 0.5A (NPN output).
Additionally, the PLC has 2 high-speed pulse input channels with a maximum frequency of 60KHz, 4 high-speed pulse output channels with a maximum frequency of 200KHz, 4 analog input channels that can measure voltage in the range of 0-10V, and optional current measurement capability in the range of 0-20mA. There are also two optional NTC temperature measurement inputs that can measure temperatures up to 150°C or 210°C. The PLC also has 2 analog output channels that can output voltage in the range of 0-10V or current in the range of 0-20mA synchronously.
The communication ports available on the PLC are RS232 for one-way program download and touch-screen communication and RS485 for two-channel MOSDBUS RTU/RS program download and touch-screen communication. Finally, an optional weighing function is also available.
Overall, this PLC is suitable for a variety of industrial applications that require high-speed input and output capabilities, as well as analog measurement and communication functions.
