INTESIS INMBSACA004I000 Bosch Commercial and VRF systems at the Modbus RTU interface - 4 units

The INTESIS INMBSACA004I000 gateway is designed to integrate Bosch Commercial and VRF air conditioning systems with Modbus RTU (RS-485) networks, facilitating efficient bidirectional communication.

Key Features

This device allows you to control up to 4 indoor units, making it ideal for commercial and industrial applications.

Connectivity

The gateway connects directly to the indoor or outdoor unit of the air conditioning system, allowing not only the control of the main functions of the AC, but also the detailed management of operations.

The connections are made through three plug-in terminal blocks:

• XY: for direct connection with the indoor unit of the air conditioner.
• V1V2: for the power supply.
• AB: for connecting to the Modbus RTU (EIA-485) network.

Configuration and Settings

The device supports various baud rates, including 2400bps, 4800bps, 9600bps (default), 19200bps, 38400bps, 57600bps, 76800bps, and 115200bps. In addition, it allows you to set the address of the Modbus RTU slave in the range from 1 to 63.

Electrical and Mechanical Characteristics

The gateway has small dimensions (93 x 53 x 58 mm) and can be mounted on a DIN rail, wall or inside some indoor units of the air conditioner. The operating temperature is between 0°C and +60°C, with an operating humidity of less than 95% RH not condensing.

Other Features

The device includes features such as the timeout for turning off the open window, the management of the fan speed and the possibility of calculating the temperature setpoint necessary to reach the temperature desired by the user.

Up to 63 INMBSACA004I000 devices can be connected on the same network, making this gateway a scalable solution for different control and monitoring needs.
