The GW-7557 is a PROFIBUS Gateway to support PROFIBUS DP and HART protocols. It allows the PROFIBUS Master to access the HART Slave devices. These HART Slave devices can be a transmitter, an actuator, a current output device, and so forth. By using this module, users can put their HART slave devices into PROFIBUS network easily. Moreover, the GW-7557 can be applied in various harsh environments by its high isolation protection design. And it fits for the application of remote data acquisition, control, process automation, and factory automation, etc.
