1. Introduction

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.

The LX3V-4DA consumes 90mA current from the 5V power supply in LX3V main unit or active
expansion unit

Be sure to use the crimp-style terminals that satisfy the
dimensional requirements shows in the left figure.

Apply 0.5 to 0.8 N.m (5 to 8 kgf.cm) torque to tighten the
terminals to prevent abnormal operation.
