Frequently asked questions
How many sensors can an SA2-XDS support?
- The SA2-XDS is scalable from 1 to 6 SA2 smart sensor modules in a single NEMA 4X enclosure, with target gases selected by installing the appropriate factory programmed SA2 modules.
Does the SA2-XDS provide MODBUS output?
- Yes. A MODBUS slave port is available for external data connectivity and acquisition, including local on-site controls and cloud-based services. The manual lists the full register map and baud rate configuration.
How is the SA2-XDS calibrated?
- The manual documents calibration frequency, recommended calibration setup, and the complete zero and span calibration screen sequences, along with span calibration error handling and remote calibration options.
