6NH3112-3BA00-6XX1 SIEMENS Exclusive Extension Board HART/RS485 for RTU3000C Original Brand New

The SIEMENS 6NH3112-3BA00-6XX1 is a specialized extension board designed to enhance the connectivity of the energy-autonomous SIMATIC RTU3000C family. This HART/RS485 interface enables the connection of up to 16 HART devices or 16 Modbus RTU devices in multidrop mode, with support for a maximum of 32 variables. It extends the functionality of RTU3000C remote terminal units by allowing integration of additional field devices via standard industrial protocols.

Overview

This module is ideal for remote stations operating without continuous power supply, such as those powered by battery or solar panels. It supports reliable data acquisition and control across remote networks, allowing communication with the control center via widely used telecontrol protocols and modern IoT protocols such as MQTT. The extension board works seamlessly with RTU3000C units to log data, send SMS or email alerts, and support time synchronization via NTP or GNSS. Remote access to HART or Modbus devices is possible using SIMATIC PDM, enhancing serviceability.
