Simplifying RS485 network design

31 August 2026 Telecoms, Datacoms, Wireless, IoT


Aipu Power has added the RS485-XXXSAV to its transceiver module range, a single-channel isolated RS485 transceiver that bundles power isolation, signal isolation, RS485 interface and bus protection into one drop-in module, aimed at simplifying RS485 network design in industrial equipment.

Rather than building an isolated RS485 stage from discrete opto-isolators and an isolated DC/DC rail, designers can embed the module directly onto the board. The RS485-XXXSAV supports data rates up to 500 Kbps, an isolation voltage of 3000 V DC, and a bus rated for up to 256 nodes, with a built-in isolated power supply so no separate isolated rail is needed on the RS485 side.

Protection is built in throughout: ESD bus protection, a switching delay of under 1 μs between send and receive, and an operating temperature range of -40°C to +85°C, positioning the module for robust, reliable communication in electrically noisy industrial environments.

Aipu Power is targeting the RS485-XXXSAV at industrial automation, smart energy and power monitoring, building automation, industrial IoT systems, security and access control, and instrumentation and data acquisition, anywhere a design needs a compact, pre-isolated RS485 node without the board space or design time of a discrete isolation circuit.
