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 www.cniacs.com 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
