Safe Remote I/O for Train Control Systems
KT8 is a safe, remote I/O box inside the modular Train Control System menTCS.The modular system platform menTCS 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).
Modular, Built-to-Order I/O Configuration
Based on modular 19" technology, KT8 provides eight slots for safe I/O cards, which can be configured as built-to-order (BTO) options. menTCS I/O cards support the common I/O requirements requested in trains. The KT series of systems provides scalable sizes of eight slots, six slots and four slots.
Part of the menTCS Train Control System
menTCS 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. menTCS 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 menTCS 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. This makes both your system costs and project schedule predictable. All KT systems have a dedicated EtherCAT component, the I/O head, for interconnection of the boxes and power supply. This in turn reduces cabling. I/O functions can still be located close to the remote actors and sensors, with fast data transmission within the menTCS. The compact format with a maximum width of 40 HP and a reduced depth compared to standard 3U systems allows installation even where space is very restricted, simplifying retrofitting of older trains.
Certification and Standards Compliance Included
Safety-related menTCS components come with certification packages and complete support for the safe operating system QNX, including safe protocols, I/O framework etc. All menTCS components that are safety-relevant are developed according to EN 50128 and EN 50129 standards and comply with all environmental requirements of EN 50155 for rolling stock: temperature class TX, shock, vibration, humidity, dust, isolation, PSU hold-up times, EMC regulations etc.
Mounting and Cooling Options
The system can be wall or rack-mounted, also on a DIN rail, and is air cooled.
