Core positioning and core advantages

The DeltaV S series large-scale connectivity solution is an efficient cabling system designed specifically for S series traditional I/O cards, enabling fast and reliable connections between field devices and DeltaV single redundant/redundant high-density I/O cards. Its core advantages can be summarized as seven key features:

Fast and error free cabinet wiring: Single redundant/redundant high-density I/O cards are connected to large-scale connection boards through ribbon cables, which can be completed within seconds without the need for tools, eliminating the need for additional cross wiring inside the cabinet and significantly reducing labor costs and wiring error risks.

Modular design enhances reliability: The connection board adopts modular signal splitting (up to 16 signals per block), which is more stable compared to traditional solutions, reduces the impact of single point failures on the overall system, and improves the reliability of the wiring system.

Reducing terminal footprint: Integrating all components required for cabinet wiring into a single connection board, combined with flexible installation methods (adapted to different cabinet layouts), significantly optimizes cabinet space utilization and reduces overall equipment footprint.

Significantly reduce manual workload: achieve flexible connection between I/O cards and connection boards based on 1:1 ribbon cables, without the need for additional cross wiring; On site equipment is directly connected to the connection board through screw terminals, simplifying the wiring process and shortening the construction period.

Significant cost reduction: Ready made ribbon cables (up to a maximum length of 3m) can be used inside the cabinet, and 6m standard circular ribbon cables can be used for cross cabinet connections, eliminating the need for customized special cables and reducing material costs; The reduction of labor and time costs further compresses overall investment.

Full signal type circuit disconnection function: The analog (AI/AO) connection board adopts a blade type disconnection design with 2mm test holes, which does not require interruption of the process when maintaining or calibrating 4-20mA circuit signals; The DI/DO connection board achieves on-site circuit power disconnection through replaceable fuses, facilitating maintenance operations.

Discrete signal terminal fault detection: When the DI/DO Plus connection board is paired with the new Plus I/O card, the DeltaV diagnostic function can detect power or cable faults; The onboard jumper supports disabling this function during process operation, facilitating rewiring and ensuring flexibility in troubleshooting and maintenance.
