Introduction to KONGSBERG RDI-32
RDI-32 Product Overview
The KONGSBERG RDI-32 is a versatile remote digital input module, available in two variants: RDI-32 xe for dry contact signals and RDI-32 axe for 24V DC/AC (50-70Hz) active signals. Designed primarily for marine and offshore installations, it serves as a key component in distributed control systems, specializing in real-time acquisition and processing of digital input signals from sensors, switches, and other field devices. The module features a maintenance-free design with no trimmers or jumpers, and all parameters are stored internally for easy remote configuration. Equipped with 32 digital input channels each with LED status indicators, it enables intuitive monitoring of signal states. Its robust construction ensures stable operation in harsh marine environments, with approvals from major classification societies like DNV, LRS, and BV, allowing direct installation on main engines or in suitable cabinets.
