Product Description
Emerson VS6907 DeltaV SIS Relay Module
- Manufacturer: Emerson
- Model/Part Number: VS6907 (also referenced as KJ2231X1-EA1)
- Description: Single Channel SIS Relay Module
Overview
- The Emerson VS6907 is a single-channel relay module designed for use in the DeltaV Safety Instrumented System (SIS). It provides reliable control for safety-critical applications, such as emergency shutdown, fire and gas detection, and process control, by interfacing with final control elements like valves or alarms in hazardous environments. The module is part of the DeltaV SIS conditioning components, ensuring compliance with functional safety standards.

Additional Information
- Functionality: The VS6907 relay module provides a single dry contact output for actuating safety devices in SIL-rated loops (up to SIL 3 with appropriate system design). It supports integration with DeltaV SIS logic solvers for precise control and diagnostics. The module does not inherently support line/load fault detection, though this may depend on system configuration.
