MPD - Railway data transmission

Description

System MPD provides transmission of logic information among several distant points and recording of this information. Data transmission could be processed one or bi-directionally.

Features

  • Modular system opens for another modification.
  • Processing and transmission of 8 or 16 binary information detected on galvanic isolated inputs of transmitter.
  • Receiving and evaluation of the information on outputs of receiver (light and acoustic indication or closing of galvanic isolated relay contact).
  • Increasing of the number of inputs and outputs by means of connection of other modules.
  • Input circuits of transmitter could be replaced by keyboards for remote addressed control of receiver outputs.
  • Recording of all transmitted data.
  • Transmission path shall be as follows:
    • LF telephone line (MPD70),
    • GSM-Public network (MPD71).

Main blocks of the system

  • Data transmitter ZVD70/71
  • Data receiver ZPD70/71
  • Display Evaluation unit ZVZ70/71
  • Recording unit ZZD70
  • Overvoltage protection unit ZPO

Parameters

  • Power supply of type SELF or network DC 9 ÷ 35V.
  • Data Inputs and Outputs and power supply connection will be protected against overvoltage (AC 5kVef/50Hz, DC shock wave 1,5kV) by means of integration of ZPO modules.
  • Coverage IP 20
  • Disposal for 24 hours operation
  • Operational temperature range -10°C ÷ +55°C
  • Relative humidity max. 75% by 30°C
