OXY-LC-485
Overview
The OXY-LC-485 is a high-performance interface board designed to drive SST Sensing's Zirconia oxygen sensors and provide a linearized digital output. It integrates barometric pressure compensation and adaptive software filtering to ensure accurate O2 measurements across a wide 0.1 to 100 percent range. Communication is handled via an RS485 interface using the industry-standard Modbus RTU protocol, simplifying integration into industrial PLC and SCADA environments.
Why Choose This Part
The board features an onboard pressure sensor that automatically corrects for barometric fluctuations, eliminating a common source of measurement error in oxygen sensing. Its Modbus RTU interface over RS485 supports long cable runs in electrically noisy industrial environments while providing high-resolution 16-bit data output.
Applications
Getting Started
Connect the board to a 8V to 28V DC power supply and interface with the RS485 A and B lines using a standard USB-to-RS485 converter or a PLC. Use a Modbus polling tool to read the input registers for oxygen concentration and pressure data. Ensure the oxygen sensor is correctly connected to the dedicated sensor port before powering the module to avoid damage.
