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
