DG-SYS4055 - PIS Coach Controller


DG-SYS4055 is a dedicated Railway Passenger Information system coach controller for metro and train applications which require high service reliability and easy integration with other onboard systems. The DG-SYS4055 bases on a low power 6-core 64 bit ARM Linux application processor, which includes Duragon’s proprietary firmware for RS-485 LED passenger information display interfacing as well as the control of audio announcements.

The DG-SYS4055 typically uses Ethernet to communicate with the train master PIS controller such as the DG-HMI70-10 driver HMI. In the case of a modernisation project where no backbone Ethernet is available, Dura-Net Power line comminication modem modules can be used to connect all the train cars with a 10/100Mbit Ethenet. Strandard interfaces include RS-485 for connecting to in-coach LED displays and a MONO Power Audio output port which is capable of driving multiple 4/8 Ohm speakers. In case the speaker system uses 100V signal levels, an external audio power transformer can be used. The system can be configured to adjust the announcement volume based on to ambient noise conditions for passenger comfort.

Duragon Systems can provide customization services which can include engineering, production and certification. Contact us with your system specification and requirements.
