The PFB366 is a compact RS232 to Profibus serial gateway. The unit is housed in a 2 ½ X 3 ¼ plastic housing with mounting tabs. A 5 pin micro connector provides the Profibus interface and a 9 pin D connector provides the RS232 interface. The Profibus channel is fully isolated from the supplied power.
The PFB366 may be used to interface peripheral devices to a Profibus system. The RS232 serial stream is internally buffered, allowing a Master node to send and receive data using standard Profibus messaging.
The power is conditioned by a loss-of-ground protection circuit and applied to a non-isolated DC-DC converter to provide 5 volts @ 500 mA. A Newport NML0505S isolated DC-DC converter to provide power to the Profibus channel.
