INMBSACA032I000 – Bosch Commercial & VRF to Modbus RTU interface for 32 AC units

INMBSACA032I000 – Bosch Commercial & VRF to Modbus RTU Interface, 32 units. 

The INMBSACA032I000 Modbus interface by Intesis enables fully bidirectional communication between Bosch Commercial and VRF air conditioning systems and Modbus RTU (RS-485) networks. Supporting up to 32 indoor units in a single interface, this solution is ideal for integrating Bosch HVAC systems into centralized building automation infrastructures such as BMS, SCADA, or industrial PLC systems.

This gateway works as a Modbus RTU slave device and connects directly to the internal communication bus of the Bosch AC system. Configuration is quick and intuitive, thanks to built-in DIP switches and optional Modbus configuration, allowing fast commissioning without additional software.

Key features:

• Controls and monitors up to 32 Bosch indoor units.
• Acts as a Modbus RTU slave (EIA-485).
• Dual configuration methods: DIP-switches and Modbus commands.
• Simultaneous control by IR remote and via Modbus RTU.
• Compact design: 93 x 53 x 58 mm – easy to mount even inside AC units.
• Flexible installation: DIN rail, wall-mounted, or integrated into the AC indoor unit (depending on model).
• Window contact functionality – reduces energy usage when windows are open, helping lower HVAC operational costs.
• Total monitoring of unit data: operating mode, temperature, fan speed, error alerts, and running hours counter for filter maintenance scheduling.

The INMBSACA032I000 is especially suitable for medium and large-scale projects where centralized HVAC integration is essential. It empowers facility managers to optimize comfort, performance, and energy consumption through direct Modbus communication without intermediary systems.

Additional specifications:

• Power supply: from the AC system's internal bus
• Operating temperature: -10°C to +70°C
• Humidity: 5% to 95%, non-condensing
• Warranty: 36 months
