Modular Train Control System - Safe I/O Extension with Frequency Inputs

BLUE BELL, Pa. November 2015 - To complete the product range of safe I/O boards around the MTCS Modular Train Control System, MEN is introducing the K4 board with four frequency inputs and functional safety up to SIL 4 within the MTCS system.

Safe Frequency Inputs for Train Control

The K4 delivers up to four frequency inputs connected via spring cage terminal blocks. They support operation using inverted signals and a signal frequency of 0.1 Hz to 30 kHz. With the integrated voltage supply of all connected sensors there is no need for additional power supply lines, making the K4 immediately ready for operation. As all components of the MTCS, K4 is 100% compatible to EN 50155 and hence suitable for usage in harsh environments.

The MTCS family consists of the MH50C controller unit together with the safe, SIL 4-certified F75P CPU board and up to 6 I/O cards. For more complex applications or if the places of operation are far away from each other the control unit can be extended by up to 63 remote I/O boxes.

The MH50C controller unit as well as the remote I/O boxes can be flexibly configured with the new I/O boards regarding their number and functionality. Beside the K4 also I/O boards for digital outputs and inputs will be available. All components can be plugged and removed independently from each other in a system, making it possible to exchange cards or do a new configuration very easily.

MTCS, the Modular Train Control System from MEN, builds on standardized electronics and a standardized interface to the software application, and is therefore the very first open computer platform for automatic train operation and protection. Both operators and supplier benefit from noticeably lower system costs – not only for certification but also due to independence of suppliers regarding maintenance and life cycle management.

Main Features:

  • Four frequency inputs, four signals each
  • Quadrature encoded signal input, 0.1 Hz to 30 kHz
  • Voltage supply of connected sensors
