WECON LX3V-4AD Module
1 WECON Technology Co., Ltd.
I. Introduction
The LX3V-4AD special module has four input channels. The input channels receive analog signals and
convert them into a digital value. This is called an A/D conversion; the maximum resolution is 16 bits.
The selection of voltage or current based input/output is by user wiring. Analog ranges of -10 to 10V
DC (resolution: 5mV), and/or 4 to 20mA, -20 to 20mA (resolution: 5µA) may be selected.
Data transfer between the LX3V-4AD and the LX3V main unit is by buffer memory exchange. There
are 32 buffer memories (each of 16 bits) in the LX3V-4AD.
LX3V-4AD consumes 5V voltage from LX3V main unit or active extension unit, 90mA current of
power supply.
