KONGSBERG RCU501 Remote Controller Unit

KONGSBERG RCU501 Remote Controller Unit

DESCRIPTION

RCU501 is a high performance, general purpose, real-time process control computer for use in a wide variety of system applications in both on- and offshore installations. The processor core is an embedded Power PC™ architecture and the module is approved for Ex Zone 2 applications.

FEATURES

• Single unit topology: SIL 1 compliant 

• Dual unit topology: SIL 2 and SIL 3 compliant 

• Triple unit topology 

• Ex Zone 2 approved 

• Compliant to the following protocols: 

1. Modbus (Serial and TCP) 

2. NMEA 0183 

3. PROFIBUS/PROFIsafe 

4. CAN/DeviceNet 

• 3rd party vendor specifi c protocols are available upon request 

• Power: 

1. Redundant power input with power alarm monitoring 

2. Inrush current and over-voltage protection 

• Enhanced watchdog with fail-safe function and system status output

BENEFITS

The following built-in functions minimize system downtime: 

• Extended Built-in Self- Test (BIST) for computer diagnostics and fault identifi cation during start-up and runtime 

• Prepared for online remote diagnostics 

• Prepared for online fi rmware upgrade 

• Bootable from fi le server or local fl ash memory 

• Easy installation and replacement 

1. DIN Rail mounting 

2. All connections are pluggable 3. 

3 digit address switches 

• Hot swap in redundant applications, dual and triple Hot-Standby redundancy, 1oo2 redundancy 

• Status LED indication (Normal/Error) 

• RoHS compliant

Computer performance

• RCU501 performance is application dependant and governed by process complexity, updating frequency and number of interfaced I/O. Maximum updating frequency is 50 Hz. 

• Confi guration guidelines: 

1. ESD/PSD: max. 800 I/O, F&G: max. 700 I/O both at scan rate: 1 Hz 

2. Process/ Automation: max. 2000 I/O, design advice: 1280 I/O both at scan rate: 1 Hz 

3. Anti-surge: 3 loops, Scan rate: 50 Hz 

4. Dynamic Positioning: Triple redundant DP system combined with Position Mooring. (Scan rate is adapted to signal processing and varies from 1 to 10 Hz
