KONGSBERG NORCONTROL RDI-32 REMOTE DIGITAL INPUT MODULE 8100154 REV.F3
KONGSBERG NORCONTROL RDI-32 is rack plug-in marine 32-channel remote digital input module, designed for Kongsberg K-Chief 500 / AutoChief C20 marine alarm and monitoring system, widely fitted onboard cargo vessels, offshore DP platforms and heavy-lift ships for discrete field contact signal collection and machinery status acquisition. This marine remote I/O module accepts 24VDC dry contact switching signals from limit switches, pressure switches, temperature relays and safety contactors, transmits all 32 channels digital status data back to the main automation controller via dual CANopen fieldbus network.

The marine RDI-32 module integrates independent galvanic isolated input channels, surge protection circuit, watchdog monitoring and individual channel status LED indicators, supports channel parameter configuration, event fault logging and emergency safety interlock functions complying with marine classification society automation requirements. Its discrete input acquisition & hardware diagnostics function continuously monitors 24V DC power supply, CAN bus communication and internal circuit integrity, detects cable fault, signal loss and hardware degradation, transmits RDI module fault alerts and vessel machinery monitoring network status to vessel AMS alarm console. The discrete input acquisition & hardware diagnostics ensures reliable distributed binary signal gathering for Kongsberg marine vessel automation monitoring system. It enables reliable marine RDI-32 remote digital input module operation under heavy vessel vibration and salt mist marine environments.

This Kongsberg RDI-32 module delivers stable marine 32-channel digital input performance installed inside vessel machinery control cabinet. The discrete input acquisition & hardware diagnostics adopts marine-grade PCB assembly with EMC shielding against electromagnetic interference and mechanical shock. Marine automation technicians rely on marine RDI-32 module operation to test each input channel, verify contact capture and inspect CAN network communication during routine maintenance. It adopts standard rack edge plug-in design for straightforward spare replacement and minimal marine alarm monitoring system downtime. Internal circuit boards use conformal coating to protect electronic components against salt mist, condensation and temperature fluctuation. It works cooperatively with K-Chief main controller, field sensors and ship integrated alarm monitoring system. It is widely used as distributed digital input spare hardware for Kongsberg Norcontrol marine vessel machinery alarm and monitoring automation control system maintenance and retrofit projects.
