Kontrollhode

Kontrollhode is a term used in Norwegian and some Scandinavian contexts to describe a device or module that houses instrumentation and control electronics at a point in a system where control decisions are implemented. In practical terms, a kontrollhode combines sensors, signal conditioning, actuators, and interface circuitry in a compact enclosure. It typically sits near the process point and communicates with a higher-level controller such as a PLC or SCADA system, often via standard industrial protocols.

Functions

A kontrollhode collects sensor signals (such as temperature, pressure, flow, or position), processes or conditions those signals, and translates controller commands into actuator actions (for example opening a valve, driving a motor, or adjusting a pump). It may provide power supply, fault detection, self-diagnostics, and safety interlocks. Some kontrollhodes are modular, allowing easy field replacement or expansion.

Design and applications

Variants range from simple temperature transmitters to complex valve control heads integrated with electronic valves and position feedback. In robotics and automated equipment, a kontrollhode can denote the terminal component at the end of a control loop that interfaces with actuators or sensor arrays. The exact features are defined by the manufacturer and the application, rather than by a single standard.

Context

The term is used mainly in Nordic languages and in technical documentation translated from those languages. In English-language sources, similar concepts are usually described as control unit, control module, instrument head, or end-effector control module, depending on the application.
