Description
Introduction
The Inspinia A-GRS4 is a specialized BMS addon module designed to expand hardware functionality by introducing RS485 serial communication capabilities. Engineered for board-to-board connection within Inspinia smart building hardware, this module allows integrators to link RS485 protocol networks seamlessly without adding electrical load to the communication bus. This device is part of our Accessories range.
Built with board-to-board galvanic isolation, the A-GRS4 provides electrical separation between connected circuits, enhancing system stability and protection against signal distortion. As part of Inspinia’s modular expansion ecosystem, it sits alongside companion options for KNX Twisted Pair, Zigbee, Bticino / SCS, and Inels Bus platforms.
