KT8 - Safe Remote I/O Box for MTCS Extension

KT8 is a safe, remote I/O box inside the  Modular Train Control System, and 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.

Safe, remote I/O box

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 KT8 system has 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.

All MTCS 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.

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.
