Samsung NASA air conditioners communication module for Modbus interface.
IntesisBox INMBSSAM001R100 enables full bi-directional monitoring and control of all operating parameters of Samsung NASA Air Conditioner units from Modbus RTU (RS-485) networks.
INMBSSAM001R100 is an integration gateway designed to connect Samsung NASA Air Conditioner units to building automation, BMS, or PLC systems using Modbus RTU (RS-485 / EIA-485). By exposing HVAC operation through Modbus registers, the gateway provides a consistent and repeatable interface for command, feedback, and diagnostics—helping standardize integration across multi-zone projects and simplifying commissioning in real buildings.

Technically identical product – only the name / SKU has changed.
The gateway is wired directly to the indoor unit through the F3F4 bus, while the automation side is provided via a Modbus RTU (EIA485) port on an A/B screw terminal block. This architecture supports stable access to both control and operational data, which is important in projects where HVAC supervision must remain consistent across many rooms, floors, or zones. The device supports control of main AC functions (operating mode, fan speed, temperature setpoint) and also enables monitoring of errors, alarms, and selected internal variables.
Commissioning is optimized for field work. Configuration is carried out with DIP switches, including a dedicated DIP set for Modbus RTU settings and another for additional functions. No configuration software and no external power supply are required, reducing panel complexity and speeding up installation. A consistent Modbus register mapping approach (used across AC brands) helps shorten engineering effort and improves repeatability when the same integration concept is deployed across multiple sites.
The device includes IP20 protection (IEC60529) and 1500 VDC isolation, supporting robust operation in typical technical environments. Wall mounting or DIN rail installation (EN60715 TH35) makes it suitable for control panels and service areas near HVAC equipment.
