Abstract:
An addressable solid-state relay (SSR), comprising:a process control module with a load output connection and a serial network control input connection; a solid-state relay fully disposed in the process control module and connected to switch said load output connection; a network client fully disposed in the process control module and connected to said serial network control input connection, and providing for control of the solid-state relay in response to data received from a serial process control network; wherein, the solid-state relay is electrically isolated from the network client; wherein, the network client is responsive to communications of at least one of Fieldbus, process field bus (PROFIBUS), Seriplex, smart distributed system (SDS), DeviceNet, controller area network (CAN), and Ethernet; wherein, the network client automatically configures itself to respond to communications of the at least one of Fieldbus, process field bus (PROFIBUS), Seriplex, smart distributed system (SDS), DeviceNet, controller area network (CAN), and Ethernet; wherein, the network client includes a digital signal processor able to respond to communications of the at least one of Fieldbus, process field bus (PROFIBUS), Seriplex, smart distributed system (SDS), DeviceNet, controller area network (CAN), and Ethernet; and wherein, the network client includes the digital signal processor and an associated network-personality program database for selectively responding to communications of the at least one of Fieldbus, process field bus (PROFIBUS), Seriplex, smart distributed system (SDS), DeviceNet, controller area network (CAN), and Ethernet.
