Analog output expansion module, with Modbus RTU output, 1 module MAX-MR-AO-1

Analog Output Expansion Module – Precise Control and Integration

This analog output expansion module, catalog number MAX-MR-AO-1, is a key element in automation and control systems. Designed to work with other devices via the Modbus RTU interface, it allows for effective expansion of existing system capabilities. This is an ideal solution for both professional installers and end-users looking for reliable and precise process control.

Functionality and application

The MAX-MR-AO-1 module offers four independent analog outputs that allow you to control devices requiring a voltage signal in the range of 0-10V. Thanks to this, it finds application in a wide spectrum of applications, such as:

• Proportional valve control
• Motor speed regulation
• Lighting control
• HVAC systems (heating, ventilation, and air conditioning)
• Industrial automation

Modbus RTU communication ensures easy integration with existing control systems, and compact dimensions (18 mm wide, 90 mm high, and 65 mm deep) allow for mounting in limited space. Mounting is done on a standard DIN rail, which facilitates installation and servicing.

Construction and technical parameters

The module has been designed with reliability and durability in mind. It uses screw/spring terminals for connecting wires, which ensures a secure and stable electrical connection. Operation at temperatures from -20°C to 50°C and an IP20 protection class guarantee resistance to environmental conditions occurring in typical industrial applications. The resolution of the analog outputs is 10 bits, which ensures precise process control. Current consumption at 40mA minimizes the impact on the energy consumption of the entire system. The Modbus RTU data transmission rate is configurable in the range of 1.2 to 115.2 kbps, allowing you to adapt the communication to the specifics of the network.
