I. Basic Information
Full Model: RMP420S Remote Multipurpose Input/Output
Original Factory Part Number: 319824 (S upgraded and enhanced version, base model RMP420 part number 306712) KONGSBERG
Compatible Systems: K‑Chief 600 engine room monitoring and alarm system, K‑Pos DP dynamic positioning, AutoChief remote control for the main unit, RIO400 distributed automation system for offshore platforms
Location: Large-capacity fully software-configurable field I/O station, each module integrates 32 universal channels, can flexibly switch between AI/AO/DI/DO/PT100 temperature measurement, replacing multiple single-function IO cards, significantly simplifying the layout of the engine room wiring box

Core Channel Configuration (32 Independent Programmable Channels)
Each channel is freely defined by engineering software for signal type. The maximum circuit load of a single channel is 1A:
1. Digital Signals DI/DO
DI Digital Input: 24VDC circuit, compatible with passive dry contacts, high and low side active switches, photoelectric isolation; supports break-open LFD, ground EFD fault detection
DO Digital Output: Solid-state non-contact output, 24VDC drives solenoid valves, relays, indicator lights; short circuit self-protection, pre-set fault-safe state in case of communication loss
2. Analog Signals AI/AO
AI Current: 4–20mA (pressure, level, transducer), external power supply selectable, accuracy ±0.15% FS
AI Voltage: 0–10V, 0–5V instrument signal acquisition
AO Output: 0–10V / 0–20mA, drives proportional regulating valves, frequency setpoint
3. Temperature Specialized
Natively supports PT100 thermoresistance temperature measurement, range -200℃~600℃, accuracy ±0.5℃, supports three-wire compensation cable for long-distance wiring in the engine room

Electrical Power Supply Parameters
Power Supply Voltage: 24VDC wide voltage 18~31.2VDC ship standard power supply
Typical Power Consumption of the Entire Machine: 10W
Protection: Reverse power connection, surge, overcurrent, internal hardware dual watchdog; single-channel short circuit does not affect the operation of the entire board
Terminal Specifications: Plug-in screw terminals, compatible with the maximum 2.5mm² cable, tightening torque 0.4–0.5Nm
