ICPDAS I-7510 (RS485, isolated) PNA2009-A1
The isolated RS485 repeater PNA2009-A1 is required to electrically isolate 'PACE-Bus' (RS485) signals exiting the system cabinet from the internal 'PACE-Bus' (RS485). Any short circuit that occurs outside the system cabinet will therefore not affect the internal 'PACE-Bus' (RS485).
The PNA2009-A1 requires a supply voltage of DC 24 V.
RS485 module (1 port) PN1002-A1
The 'RS485 module (1 port)' PN1002-A1 is used for a convenient connection of external 'PACE-Bus' (RS485) call stations and components. It provides the following electrically isolated signals:
- 'PACE-Bus' (RS485) communication
- DC 24 V power supply voltage with ground fault detection
- Analog audio input
- Analog audio output
Any short-circuit on the connected wiring which occurs outside of the system cabinet will therefore not affect the internal signals.
One PN1002-A1 plug-in module can be mounted on a digital audio matrix board.
RS485 module (1 port, DIN rail) PN2009-A1
The RS485 module (1 port, DIN rail) PN2009-A1 is used for a convenient connection of external 'PACE-Bus' (RS485) call stations and components. It provides the following electrically isolated signals:
- 'PACE-Bus' (RS485) communication
- DC 24 V DC/DC converter with integrated ground fault monitoring
- Analog audio input
- Analog audio output
Any short circuit on the connected wiring which occurs outside of the system cabinet will therefore not affect the internal signals.
