KT8 is a safe, remote I/O box inside the duagon SAFE CONTROL (d-SC) System.The modular system platform d-SC is usable for safety-critical train applications like train control, automatic train operation (ATO) and automatic train protection (ATP) up to SIL 4 (EN5012x) or SIL 3 (IEC61508).

The KT8 system consists of the head unit K100 and d-SC I/O board slots. The I/O boards are completely configurable and all system components are directly linked via Ethernet over the backplane. The head unit K100 provides the EtherCAT connections to other d-SC system boxes, the power input for the system and two hex switches. With the hex switches of the K100 the unique chassis ID within an EtherCAT network is defined.

Modular I/O Configuration

Part of the duagon SAFE CONTROL System

d-SC is a modular SIL 4 certifiable family of CompactPCI-based standard products usable for every kind of safety-critical railway application - from a single function to the main control system of the train. It can be configured to control anything in the train that requires functional safety - under SIL 4, SIL 3 or SIL 2 requirements. d-SC communicates via standard EtherCAT real-time Ethernet and interfaces to any type of consist fieldbus network like MVB, CANopen, Profinet etc. This makes it easy to integrate into a TCN network as well as into regionally different Train Control Systems like ETCS, CTCS, ATCS or Klub-U. The high level of flexibility of d-SC results in significant cost and time savings during computerization of the train.

Compact and Cost-Saving Remote I/O

Being modular and SIL 4 certifiable, the KT series reduces the certification risk and efforts.
