Kongsberg RDIOR420 Remote Digital Input/Output and Relay

The RDIOR420 is a combined I/O module with 16 solid-state DI/DO and 16 relay channels for KM automation systems.

The 32 I/O channels are connected to the host control computer (RCU) via a redundant I/O process bus.

Functions

- 16 individually configurable solid-state digital input or output channels

- 16 relay channels, NC/NO.

- Dual remote I/O process bus interfaces (RBUS A and RBUS B) for redundant communication with the host computer.

- Communication ports are insulated from other module circuits.

- Short-circuit protected I/O loops on solid-state output channels.

- Loop monitoring for 16 solid-state channels.

- Communication ports are isolated from other module circuits.

Advantages

- Overvoltage protection

- Extensive module diagnostics

- Input/output channels can be configured on-line

- Soft and hard fault protection

- Line fault detection (solid-state I/O only)

- Fail-safe activation of outputs in case of loss of communication with host computer

- Self-test function

- Easy to install and replace

- Simple and safe FW upgrade

- Status LEDs
