Description
KONGSBERG RMP400 603129
Technical Specifications Brand: KONGSBERG Model: RMP400, part number 603129 Power Supply: 24 VDC Signal Types: 4-20 mA analog input, digital input, relay digital output Fieldbus: Redundant Kongsberg control bus Channel Isolation: Galvanic isolation between field channels and backplane Protection Grade: IP20 for cabinet installation Operating Temperature: -25°C ~ +70°C Humidity: 5% to 95% non-condensing
Functional Features Combined analog and discrete signal processing on single module. Redundant bus communication path prevents communication loss on single cable fault. Continuous diagnostics of field wiring for open circuit and short circuit. Hot-swap capability for online replacement without shutting down whole automation system. Front panel LED array shows module power, bus link and individual channel health status. Each channel has independent signal conditioning circuit to reduce cross talk. Compliant with marine shock, vibration and salt mist environment standards.
Application Scenarios Offshore platform process monitoring, ship cargo control system, marine engine room automation, safety instrument system signal collection for floating units, valve remote control on FPSO vessels.
Performance Parameters High precision analog signal sampling for 4-20mA transmitters. Rapid fault detection for field instrument loops. Redundant bus maintains uninterrupted communication under single cable damage. Strong immunity against electric noise from marine power and propulsion equipment. Long service life under continuous offshore salt atmosphere environment.
Material Composition Front panel: flame retardant black ABS plastic. Main PCB: multilayer FR4 board with conformal coating for salt mist protection. Core electronic parts: precision AD converter, opto-couplers, bus communication chip, industrial relays. Backplane connector: gold plated edge connector for reliable contact under vibration. Indicator: SMD high brightness LED.
Structural Features Rack mount plug-in card form factor, rear gold finger interface to system backplane. PCB layout separates analog signal area, digital signal area and power area. Every channel has dedicated signal conditioning circuit to eliminate cross interference. Latch clips on both sides for fast installation and removal.
Working Principle Field analog transmitters and binary switches connect to module terminal blocks. Analog signals pass signal conditioning and isolation circuit before AD conversion to digital value. Digital input signals go through opto-isolation to filter noise. All collected data packages transmit over redundant fieldbus to central Kongsberg controller. The module receives control command and drives relay outputs to operate field actuators. If wire fault or channel hardware failure appears, diagnostic information uploads immediately to alarm management station.
Installation Requirements Insert module into rack slot with power turned off and lock latches. Use shielded twisted pair cables for field instruments, single point shield grounding. Separate instrument cables from heavy power cables and motor wiring. Complete module hardware configuration after installation and perform channel loop test. Maintain cabinet ventilation to avoid heat accumulation inside rack.
Usage Notes Never connect high voltage signal to low voltage I/O terminals. Inspect terminal screw tightness periodically, vessel vibration loosens terminals. Follow Kongsberg service manual during hot swap maintenance. Anti-static wristband must be worn while handling circuit card. Re-calibrate analog channels after module replacement.
