Introduction

KT8 is a safe, remote I/O box inside the Modular Train Control System MTCS. It is a modular system platform usable for safety-critical train applications like train control, automatic train operation (ATO) and automatic train protection (ATP) up to SIL 4.

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. MTCS I/O cards support the common I/O requirements  requested in trains. The KT series of systems is available with scalable sizes of eight slots, six slots and four slots.

Part of the MTCS Modular Train Control System

MTCS 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. MTCS communicates via standard 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 MTCS 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 real-time Ethernet 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 MTCS. The compact format with a maximum width of 9.5 inches (half 19") 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 MTCS components come with certification packages and complete support for the safe operating system QNX, including safe protocols, I/O transfer layer etc. All MTCS components that are safety-relevant are developed according to EN 50128 and EN 50129 standards and complies 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 cooled by natural convection. Cooling is independent of the mounting
