Danfoss 080G0255 MCX061V Programmable HVAC/R Controller

Product Overview

The Danfoss 080G0255 MCX061V is a compact programmable HVAC/R controller featuring a 24 VAC power supply, integrated LCD, Ethernet connectivity and an embedded electronic expansion valve driver. It is designed for refrigeration and air-conditioning equipment requiring coordinated compressor, fan, pump, valve and superheat control.

Compared with basic MCX061V versions, the 080G0255 adds Ethernet communication while retaining CANbus and RS485 Modbus connectivity. This makes it suitable for applications requiring local controller networking, remote system integration or connection to compatible monitoring equipment.

Main Features

• Original Danfoss MCX061V controller.
• Danfoss ordering number: 080G0255.
• 24 VAC power supply.
• Integrated LCD and real-time clock.
• 7 analog inputs and 8 digital inputs.
• 3 analog outputs and 8 digital outputs, including 6 relay outputs.
• One integrated electronic expansion valve driver.
• Ethernet, CANbus and RS485 Modbus communication.
• DIN-rail mounting in an 8-module enclosure.
• Suitable for networked HVAC/R and refrigeration control systems.

Technical Specifications

Compatible System and Applications

The controller is suitable for chillers, reversible heat pumps, refrigeration units, condensing systems and other HVAC/R equipment. Its integrated electronic valve driver can support superheat-control applications when used with a compatible valve, sensors and approved control program.

Ethernet, CANbus and Modbus interfaces provide multiple integration options. Actual remote-access, monitoring and supervisory functions depend on the application software, network configuration and connected system.

Maintenance and Replacement Notes

Verify that the replacement controller requires the 24 VAC Ethernet version. Other MCX061V products may use a different power supply or may not include Ethernet. Matching only the MCX061V family name is not sufficient for direct replacement.

Confirm the complete 080G0255 ordering number, firmware or BIOS version, application file, parameter set, sensor configuration and electronic valve requirements. Programming and commissioning may be required after installation.
