KONGSBERG NA-1E220 Single Board CPU

Product Details

NA-1E220 Product Description

The KONGSBERG NA-1E220 is a single board CPU module engineered for deployment within the KONGSBERG NA Series distributed control and automation platform. Designed to serve as the computational core of a modular control rack, the NA-1E220 delivers deterministic scan-cycle execution, structured program management, and coordinated I/O arbitration across multi-rack architectures. Its role within the control layer makes it a foundational component for system integrators, OEM panel builders, and maintenance engineers who require a verified, pre-tested CPU replacement or expansion unit with a confirmed 12-Month Warranty and immediate inventory availability.

The NA-1E220 does not operate in isolation — its value is fully realized when integrated within a coherent KONGSBERG NA Series automation architecture. At the control layer, the NA-1E220 coordinates directly with the NA Series rack backplane, which distributes power and data signals to all co-resident modules. The power layer is typically served by a dedicated NA Series power supply module, ensuring regulated DC voltage across the CPU and all I/O cards without cross-interference.

At the I/O layer, the NA-1E220 interfaces with NA Series digital input modules, digital output modules, and analog I/O cards that handle field-level signal acquisition from sensors, transmitters, and actuators. Signal integrity across these layers depends on proper backplane seating and module addressing, both of which the NA-1E220 manages through its onboard bus controller. For applications requiring signal isolation — particularly in high-noise environments such as motor control centers or variable frequency drive panels — signal isolator modules are recommended between field wiring and the I/O rack to protect the CPU's scan integrity.

At the communication layer, the NA-1E220 supports integration with KONGSBERG communication gateway modules that bridge the NA Series platform to external supervisory systems via protocols such as Modbus RTU, Modbus TCP, or proprietary KONGSBERG network interfaces. This enables the NA-1E220 to participate in plant-wide SCADA architectures, feeding real-time process data upward to historian servers or DCS operator stations without requiring additional protocol converters in most standard configurations.

For HMI integration, the NA-1E220 can be paired with panel-mount or rack-mount HMI terminals that communicate via the system's serial or Ethernet ports, providing operators with real-time visualization of control logic states, alarm conditions, and process variable trends. In redundant architectures, a secondary CPU module — such as a hot-standby NA Series CPU — can be configured alongside the NA-1E220 to ensure bumpless transfer in the event of a primary CPU fault, a critical requirement in continuous process industries such as petrochemical refining, offshore marine automation, and power generation.

At the execution layer, the NA-1E220 coordinates output commands to relay output modules, motor starter interfaces, and variable speed drive enable signals. In packaging line and conveyor applications, this coordination ensures synchronized motion sequencing across multiple drive axes. In water treatment and utility automation, the CPU manages pump sequencing, valve actuation, and flow control loops with the determinism required for regulatory compliance.

Maintenance engineers benefit from the NA-1E220's modular architecture: the CPU can be extracted and replaced without disturbing adjacent I/O modules or field wiring, reducing mean time to repair (MTTR) significantly compared to integrated controller designs. Diagnostic capability is further enhanced when the NA-1E220 is used alongside NA Series diagnostic or status modules that provide LED-based and software-readable fault indication at the rack level.

Marine & Offshore Automation: KONGSBERG has a strong heritage in marine automation systems. The NA-1E220 is well-suited for vessel automation panels controlling ballast systems, cargo pump sequencing, engine room auxiliaries, and dynamic positioning support systems where deterministic control and compact rack footprint are essential.

Power Generation & Utilities: In power plant auxiliary control panels — covering cooling water systems, fuel oil transfer, and generator excitation support — the NA-1E220 provides the reliable scan-cycle execution needed for interlocked protection logic and sequential start/stop automation.

Petrochemical & Process Industries: For process skids handling compressor control, heat exchanger regulation, and separator level management, the NA-1E220 integrates into multi-rack NA Series architectures that span field junction boxes, marshalling cabinets, and central control rooms.

Mining & Metallurgy: In conveyor drive control panels, crusher sequencing systems, and ore processing automation, the NA-1E220's robust industrial design supports continuous operation in high-vibration, high-dust environments when properly enclosed in IP54 or higher rated control cabinets.

Packaging & Discrete Manufacturing: For OEM machine builders requiring a compact, proven CPU platform with long-term spare parts availability, the NA-1E220 offers a stable hardware baseline that supports multi-year production runs without forced hardware migration.

Q1: Is the NA-1E220 compatible with existing NA Series racks and I/O modules already installed in the field?Yes. The NA-1E220 is designed for the KONGSBERG NA Series modular rack platform and is compatible with the standard NA Series backplane bus. It can be installed as a direct replacement for a failed CPU or as an expansion unit in a multi-rack system. Integrators should verify firmware revision compatibility with existing I/O modules and confirm rack slot addressing prior to commissioning. Our pre-shipment testing process validates basic hardware functionality before dispatch.

Q2: What warranty and support terms apply to the NA-1E220?Every NA-1E220 unit supplied by NANKMOS carries a 12-Month Warranty covering hardware defects identified under normal operating conditions. Units are pre-tested prior to shipment to confirm board-level functionality. In the event of a warranty claim, replacement or repair coordination is handled directly. For long-term maintenance planning, we recommend holding at least one spare CPU module per installed rack system to minimize unplanned downtime exposure.

Q3: How should the NA-1E220 be integrated into a redundant control architecture?In redundancy-critical applications, the NA-1E220 can serve as either the primary or secondary CPU in a hot-standby configuration, depending on the NA Series rack design and firmware support for redundancy switchover. The communication layer between primary and standby CPUs typically uses a dedicated synchronization link or shared backplane segment. Integrators should consult the NA Series system architecture documentation and validate switchover timing against process safety requirements before commissioning redundant configurations in live plant environments.
