The LX3V-4DA analog special function block has four output channels. The output channels take a digital value and output an equivalent analog signal. This is called a D/A conversion. The LX3V-4DA has maximum resolution of 12bits.
The selection of voltage or current based input/output is by user wiring. Analog ranges of -10 to 10V DC (resolution:5mV), or 0 to 20mA (resolution: 20μA) maybe selected independently for each channel.
Data transfer between the LX3V-4DA and the LX3V main unit is by buffer memory exchange. There are 32 buffer memories (each of 16 bits) in the LX3V-4DA.
