RDIOR420-Remote Digital
Input/Output and relay
RDIOR420 is a combined I/O module containing 16 solid-state DI/DO and 16 relay
channels for use in KM automation systems.
The 32 I/O channels are interfaced towards the host control computer (RCU) by 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 interface (RBUS A and RBUS B) for redundant
communication with the host computer(s).
• Communication ports galvanically insulated from other module circuitry.
• Short-circuit protected I/O loop on solid-state output channels.
• Loop monitoring on 16 solid state channels.
• Communication ports galvanically insulated from other module circuitry.
