Emerson DeltaV ™ M-series Traditional I/O

Emerson DeltaV ™  M-series Traditional I/O

Core positioning and core advantages

The DeltaV M series traditional I/O is a modular process control system I/O subsystem that focuses on "on-site installation, low-cost deployment, and high availability". It is suitable for industrial scenarios that require flexible expansion and reliable operation. The core advantages can be summarized as four key features:

Reduce capital equipment costs: The entire system is designed to be modular and supports live installation (refer to specific area installation guidelines). I/O interface carriers and interfaces can be flexibly added or removed according to 4/8/16/32 channel groups to avoid overinvestment; The compact design of I/O components allows for installation in on-site junction boxes, reducing the footprint of control room equipment; On site installation reduces long-distance wiring of multi-core cables, integrated design eliminates grouping panels, built-in series fuses and bus power supply reduce external accessory costs.

Shortening installation time and cost: With its plug and play feature, I/O components can be directly inserted into the carrier, supporting the installation of the carrier to reserve expansion space before installing the I/O interface; Staged installation is efficient, and once the carrier is in place, on-site equipment wiring can begin without waiting for I/O card installation; The I/O interface and terminal block are equipped with function keys to ensure the correct matching of the card and terminal block, avoid accidental installation, and simplify the installation and replacement process.

Enhance productivity: Support real-time addition of devices online, without interrupting the process when adding I/O interfaces. DeltaV resource manager automatically recognizes and allocates basic configurations to ensure production continuity.

Improve process availability: Both traditional I/O and HART I/O cards support 1:1 redundancy. Redundant and non redundant use the same series of second-generation I/O cards, which can reuse existing I/O and spare parts investments. Redundant channels do not require additional configuration, and the wiring of redundant terminal blocks is consistent with that of single terminal blocks, without the need for additional wiring; The system automatically recognizes redundant I/O, and redundant card pairs are displayed as single cards in the system tool, simplifying configuration; When the main I/O card fails, it automatically switches to the backup card without manual intervention, and the operator interface will clearly indicate the switching status.

Core components and functional details of the product

（1） Core hardware components

The I/O interface carrier is mounted on a DIN rail surface and supports modular expansion of all I/O related components. It can be installed live (in specific scenarios), providing a foundation for the installation of I/O cards and terminal blocks

Power supply AC to 24V DC large capacity power supply, integrated design for on-site equipment power supply, reducing external power configuration requirements

The I/O interface consists of an I/O card and an I/O terminal block. The I/O card supports multiple signal types, and the terminal block is adapted to different wiring requirements. The two are matched through function keys to prevent accidental installation

The I/O card features a unified design for analog (AI/AO) and discrete (DI/DO) series, making it easy to insert into the carrier; Equipped with power supply and internal fault indicator light, the 8-channel card is equipped with channel status LED; Compliant with ISA G3 anti-corrosion standards (high-quality components+conformal coating)

The I/O terminal block is installed on the carrier and supports pre wiring of multiple types to adapt to different I/O cards. Some include fuses, while redundant terminal blocks support installation of redundant card pairs. Some can be paired with large-scale terminal blocks to connect third-party wiring solutions

（3） Redundant switching mechanism

Switching triggering scenarios: hardware failure of the main card, communication failure between the main card and the controller, on-site wiring failure, and manual triggering through the diagnostic resource manager.

Switching performance: Redundant I/O card switching is completed within 2 scanning cycles of the I/O bus; The 'first on, then off' contact ensures continuous power supply for digital field devices, and the analog output signal is briefly driven by the dual card during switching (<5ms) without process disturbance.

Fault alarm and recording: Hardware alarms automatically report integrity errors between the primary and backup cards, switch events are recorded in the system event log, control module level timestamps record log events and alarms, and SOE cards can provide higher resolution (± 0.25ms/card) event recording.

Convenience of maintenance: In safe areas, faulty cards can be replaced with electricity, while in hazardous areas, specific installation procedures must be followed; The new backup card is automatically debugged and activated by the system.
