Kongsberg RDIO400 Remote Digital Inputs and Outputs

The RDIO400 is an interface module between the serial process bus and digital input or output signals.

Description

The Kongsberg Maritime Remote Input/Output System (RIO400) interfaces via the Serial Process Bus (SPBus)

connecting control computers in the process network with input and output (I/O) signals from remote devices such as valves, relays and temperature sensors.

The RDIO400 is an interface module between the SPBus and the digital inputs or outputs of eld devices.

The RIO400 system provides a cost-effective solution for connecting any number of inputs and outputs to the Kongsberg Maritime Automation system.

independent of the distance between the remote device and the controller computer.

Functionality

- Up to 32 independent go to 

- Dual serial process bus (SPBus) interfaces, allowing optional redundancy

- Each SPBus interface ensures electrical isolation from the control system.

- Easy to install and replace:

- DIN rail mounting

- Plug-in connection

- LED status indicator for normal operation or error status

- Loop checking and commissioning from the operating station and local data terminals possible

- Short-circuit proof loop current driver

- Safe start-up of outputs in case of communication breakdown

- Built-in tests for self-diagnosis and fault identification c

- SIL 1 compliant

- Line fault detection (LFD)

- Ground fault detection (EFD)

- Dual watchdog
