Description
The Kongsberg 306712 is the RMP420, a 32 channel multipurpose I/O module for Kongsberg alarm monitoring and integrated control systems. Each channel is set in software as an analogue or digital input or output, including 0 to 10 V and 0 to 20 mA signals and 2 or 3 wire PT100 sensors, and two channels can count pulses up to 10 kHz or read an encoder. It connects to its RCU controller over two galvanically isolated RBUS ports, monitors every loop, and moves outputs to their fail safe values if communication is lost. It runs on 24 V DC at 10 W typical and is ATEX certified for zone 2 (Presafe 18ATEX12094X).
Application: Alarm monitoring and integrated control systems on Kongsberg RBUS, including hazardous area zone 2
Used with: Kongsberg RBUS with an RCU remote controller unit such as the RCU602
What is the RMP420 306712 used for?
The RMP420 brings field signals into Kongsberg alarm monitoring and control systems: temperatures, pressures, levels, valve feedback and pump commands. Because every channel is configured in software, one module type covers a mix of signals in a cabinet.
Key features
- 32 channels, each configured as analogue or digital input or output
- PT100 inputs, 2 or 3 wire, -200 to 600 °C
- Two channels for pulse, frequency or encoder inputs
- Loop monitoring on every channel
