INMBSMIT050C000 – Mitsubishi Electric to Modbus RTU/TCP Gateway for 50 Groups

INMBSMIT050C000 – Mitsubishi Electric to Modbus RTU/TCP Gateway for 50 Groups. 

The newer version of this device is IN770AIR00SO000.

The INMBSMIT050C000 IntesisBox gateway is a powerful and flexible solution designed to enable bidirectional communication between Mitsubishi Electric City Multi air conditioning systems (RAC, PAC, VRF) and Modbus networks, both RTU and TCP. Supporting up to 50 indoor unit groups, this gateway offers seamless integration with BMS, SCADA, and PLCs using Modbus protocols.

The interface is fully compatible with Mitsubishi Electric controllers such as AG-150A, G-50A, GB-50A, GB-50ADA, AE-200, and EW-50. The INMBSMIT050C000 connects directly to the outdoor unit communication bus, enabling complete access to all indoor units. Not only does it provide control over essential HVAC parameters like operation mode, setpoint temperature, or fan speed, but it also allows reading of internal parameters from the outdoor units, supporting diagnostic and efficiency monitoring functions.

Configuration and commissioning are made easy using the Intesis MAPS software. With advanced features like automatic unit scanning and real-time diagnostics, the integration process becomes simple and error-free. Installers can define custom communication parameters, map Modbus registers, and test the system from a single interface. The robust diagnostic tool helps detect malfunctions quickly, reducing downtime and improving maintenance processes.
