What is the Emerson DeltaV Fieldbus H1, Series 2?
The Fieldbus H1 Series 2 is a digital communication interface module used to link field instruments to the DeltaV DCS through the Foundation Fieldbus protocol. With its 31.25 kbps operation, the H1 Fieldbus segment supports two-way communication and device power over one pair of wires — significantly lowering wiring complexity and increasing efficiency.
Key Features:
- High-speed digital communication by Foundation Fieldbus H1 protocol.
- Series 2 reliability, providing hardware upgrade and extended lifecycle support.
- Less wiring cost with a single-cable solution for power as well as data.
- Better diagnostics that enhance visibility into field device performance and process conditions.
- Hot-swappable modules, with minimal downtime for maintenance.
Why Select Fieldbus in Place of Traditional I/O?
Fieldbus H1 is a better choice than traditional analog I/O systems because it can transmit rich diagnostic and status information in addition to control signals. With Fieldbus H1:
- Engineers are able to monitor and set up devices remotely from the control room.
- There is considerable less control cabinet space with fewer wiring terminals needed.
- Data accuracy is better, minimizing signal degradation typical of analog systems.
The Series 2 module complements these advantages further with increased processing power, firmware updates, and enhanced integration capabilities with DeltaV systems.
Applications of the DeltaV Fieldbus H1 Series 2
The DeltaV Fieldbus H1, Series 2 is applied across process industries such as:
Oil & Gas: Providing safe and reliable pressure, temperature, and flow sensor monitoring in hostile environments.
Pharmaceuticals: Offering accurate control of batching and formulation processes with traceable information.
Chemical Processing: Providing real-time process adjustments with minimal delay.
Power Generation: Optimizing turbine and boiler performance with integrated device control.
Due to its support for a broad spectrum of field devices, this module integrates easily into both legacy and modernized plant infrastructures.
