INMBSACA008I000 – Bosch Commercial & VRF to Modbus RTU interface for 8 indoor units

INMBSACA008I000 – Bosch Commercial & VRF to Modbus RTU Interface, 8 units. 

The INMBSACA008I000 gateway by Intesis enables full bi-directional communication between Bosch Commercial and VRF air conditioning systems and Modbus RTU (RS-485) networks. Designed for integration into building automation systems (BMS, SCADA, PLCs), it allows for precise control and monitoring of up to 8 indoor units from a central system.

This interface operates as a Modbus RTU slave device and connects directly to the internal communication bus of the Bosch units. Configuration is fast and simple using onboard DIP switches, eliminating the need for a computer or additional software during commissioning. Its compact size makes it easy to install even in tight spaces, including inside compatible indoor units.

Key features:

• Supports up to 8 Bosch indoor units in a single interface.
• Acts as a Modbus RTU slave using EIA-485 protocol.
• Quick installation with DIP switch configuration – no PC required.
• Simultaneous control via IR remote and Modbus RTU commands.
• Supports DIN rail, wall, or in-unit mounting (depending on model).
• Window contact input enables energy savings by switching off AC when windows are open.
• Full access to AC unit’s internal data: operating mode, fan status, temperature, error codes.
• Built-in hour counter for filter maintenance scheduling and service alerts.

This compact device (93 x 53 x 58 mm) is ideal for centralized energy management in hotels, offices, retail, or commercial buildings. By integrating with Modbus systems, operators can reduce HVAC costs and improve control efficiency.

Additional specifications:

• Power supply: via AC communication bus
• Operating temperature: -10°C to +70°C
• Humidity: 5% – 95%, non-condensing
• Warranty: 36 months
