Product Description

The Waveshare Modbus RTU Module (A) is an industrial voltage regulator module designed for RS485-based Modbus RTU systems. The module operates from a wide DC 7V to 36V supply and combines mixed input and output functions in a rail-mount flame-retardant PC enclosure.

The module provides 2 relay outputs, 2 digital inputs, 2 analog current outputs, and 2 analog current/voltage inputs. According to the source data, it integrates multiple protection functions including power isolation, magnetic isolation, a resettable fuse, and TVS suppression for transient overvoltage, surge, and ESD-related events. Communication is handled through the Modbus RTU protocol, and the device address is configurable from 1 to 255.
