Description

The OXY-LC Interface Electronics unit is designed to power and control SST’s zirconia oxygen sensor range, delivering reliable performance across a variety of applications.

Users can choose from multiple configurable output formats including RS485, PWM, 0–10 VDC, and 4–20 mA. The RS485 Modbus RTU protocol provides enhanced functionality—enabling full control of sensor settings and access to detailed information such as sensor diagnostics, barometric pressure, and internal temperature readings.

Advanced adaptive software filtering ensures a fast yet stable oxygen measurement response. The OXY-LC also delivers a precise, linear output across the full range of SST’s zirconia sensors.

Featuring a built-in barometric pressure sensor and interface-mounted screw terminals, the unit offers easy installation along with protection against incorrect wiring and electrical surges.
