The WECON LX3V-4AD is a 4-channel analog-to-digital (A/D) converter expansion module designed for WECON LX3V series PLCs. It features 12-bit resolution and converts analog voltage ((-10text{V}) to (10text{V})) or current ((4-20text{mA}) or (-20text{mA}) to (20text{mA})) signals into digital values via buffer memory exchange. The module is ideal for precise industrial automation data acquisition. Key Features and Specifications: Channels: 4 independent analog input channels.Input Ranges: Configurable for (pm 10text{V}) DC or (pm 20text{mA}) (including (4-20text{mA})).Resolution: 12-bit maximum.Communication: Data exchange with the PLC via 32 buffer memories.Power Supply: Consumes (90text{mA}) (5V) from the main unit and requires (24text{V}) DC external power.Indicators: Features LED indicators for Power, Communication (Com), and Operating Status (State).Functionality: Supports configurable averaging of data to stabilize readings. Wiring and Configuration: Input signals (voltage or current) are selected via user wiring on the terminal block.The module can be configured using BFM (Buffer Memory) locations to define gain/offset values for calibration. Application:The module acts as a bridge to convert physical, analog, environmental parameters (like pressure, temperature, or speed) into a digital format for the LX3V PLC to process.
