The AS02366 is a compact RS232 to Profibus serial gateway. The unit is housed in a 21/2 x 31/4 inch plastic housing with mounting tabs. A standard DB9-Female connector provides the Profibus interface and a DB9-Male connector provides the RS232 interface.

The Profibus channel is fully isolated from the supplied power. The power is conditioned by a loss-of-ground protection circuit.

The AS02366 maybe used to interface peripheral serial devices to Profibus system. The RS232 serial stream is internally buffered allowing a Master node to send and receive data using standard Profibus messaging.

The AS02366 provides a fully buffered serial interface between Profibus and peripheral devices. Internal FIFO’s, buffer up to 255 bytes for both receive and transmit data, easing the interface for slower RS232 based devices. Hardware or software flow control is supported.

The AS02366 replaces the PFB366 and is backwards-compatible.
