Fewer control cabinets: Interface and marshalling combined in a compact design

Universal I/O systems offer signal flexibility through software-based channel configuration. However, they do not completely break down the rigid structure of the levels.

VIP I/O-Marshalling combines the interface level and marshalling level in a modular system that can be configured flexibly. The streamlined architecture eliminates the need for large marshalling cabinets and signal-specific I/O cards. This makes it possible to use smaller cabinets even when there are many signals.

Up to 30% shorter project lead times through flexible engineering

Planning, installation, and testing – regardless of the signal type – enable projects to be handled in parallel. To start the project, all you need to know is the number of I/O signals. The signal type remains flexible and can be defined at any time using appropriate I/O plug-in modules. This significantly speeds up implementation.

Please refer to the note regarding product selection.

Wide signal spectrum, including Ex i, SIL

The VIP I/O marshalling plug-in modules support all common signal types. In addition, the Ex i versions have many international Ex approvals for use in all Ex zones and for all substance groups.
Many types of plug-in modules offer functional safety in accordance with SIL IEC/EN 61508, even in standard applications. The products have a safety integrity level ranging from SIL 2 SC 3 to SIL 3. SIL coupling relays are used for safe emergency shutdown in safety applications.

Compact integration of surge protection

Studies (Jensen et al., 2023; Romps et al., 2014; NASA) predict an increase of about 12% in lightning activity for every degree of global warming. As a result, the need for reliable surge protection for MCR technology is increasing, particularly for critical infrastructure such as offshore platforms, LNG terminals, and pipelines.

With the overvoltage protection (OVP) termination board and the corresponding TTC modules, you can effectively protect every signal circuit while saving space – integrated directly onto the board, with plug-and-play. This is how you can protect your system against climate-related risks in the long term and ensure maximum availability of your MCR systems.

Decentralized installation

Decentralized installation of VIP I/O-Marshalling in a remote control box reduces wiring effort, shortens field cable runs, and reduces the load on central control cabinets. Signals are acquired close to the process, conditioned, and transmitted in a structured format to the control level. Depending on the system design, the universal I/O system is installed either decentrally in a remote control box or centrally in the supervisory control system cabinet.

Centralized installation

In centralized signal processing, all field signals are consolidated and processed in a central control room. This allows maintenance and service work to be carried out efficiently in one location. Depending on the system design, VIP I/O-Marshalling and universal I/O systems are either integrated together in a single control cabinet or installed in separate control cabinets.

Signal conditioning and marshalling for universal I/O systems in Ex areas

In the chemical and petrochemical industries, as well as in mills, silos, and food production facilities, gases, vapors, mists, or dusts can create explosive atmospheres. Therefore, electrical devices in Ex areas are subject to special directives, which include the ATEX, IECEx, NEC/CEC, and UL certifications and directives.

The figure shows selected installation options for the VIP I/O-Marshalling signal marshalling system, including signal conditioning based on the zone concept. The field devices are always located in the Ex area: zone 0, 1, or 2.

Installation outside of Ex zones

The VIP I/O-Marshalling solution is installed in an IP20 control cabinet in the safe area. Intrinsically safe field devices from zones 0, 1, and 2 can be connected directly.

Installation in zone 2

Installation in zone 2 using the Ex e-certified VIP I/O-Marshalling solution, in compliance with additional requirements, such as installation in a control cabinet with at least IP54. Intrinsically safe field devices from zones 0, 1, and 2 can be connected directly.

Installation in zone 1

Installation of the VIP I/O-Marshalling solution in zone 1 with additional Ex d type of protection. This requires housings that act as “flameproof enclosures”. Intrinsically safe field devices from zones 0, 1, and 2 can be connected directly.

Note regarding product selection

The compatibility of I/O plug-in modules and termination boards depends on the specific model. As a result, technical data and the scope of functions may vary depending on the combination. Check the details in the product documentation or use the configurator to select the right combination.
