RS-GIO is a universal input/output module that adopts a modular design. The bottom is connected through an IO (CAN) bus and communicates with the controller through a CM communication module to form an IO station. An IO station generally supports 10 IO cards. The module is encapsulated in flame-retardant engineering plastic, and the circuit design has strong electromagnetic interference resistance, making it particularly suitable for the field of safety data acquisition. RS-GIO is a high-end intelligent IO module that can perform data front-end filtering, engineering quantity conversion, and self diagnosis. There are indicator lights on the panel to display the status, supporting external power supply and isolation.
