Additional Information
- Functionality: The VE4035S2B1 delivers eight 4-20 mA analog output channels with HART communication for precise control and diagnostics of field devices. Its redundant design ensures uninterrupted operation by switching to a backup module if the primary fails. The module supports hot-swappable installation, enabling maintenance without system downtime.
- Environmental Durability: Designed for harsh industrial environments, the module features conformal coating to protect against airborne contaminants and operates reliably in extreme temperatures, shock, and vibration conditions.
- Integration: The VE4035S2B1 integrates with DeltaV M-series systems, mounting on T-type DIN rail I/O carriers, such as VE4050S2K1C0. It is suitable for hazardous area installations, including Zone 2, and complies with DeltaV installation guidelines. The HART protocol supports advanced device management and diagnostics.
- Availability: Available through suppliers as new, surplus, or refurbished units, typically with a one-year warranty. Users must verify compatibility with DeltaV software versions and ensure proper carrier configuration.
