Danfoss 080G0042 MCX15B Programmable HVAC/R Controller

Product Overview

Danfoss 080G0042 MCX15B is a legacy programmable electronic controller for refrigeration, air-conditioning and HVAC/R applications. It provides 15 digital outputs and supports CANbus, RS485 and Modbus communication for integration with local control networks and supervisory systems.

The controller was designed for programmable OEM equipment requiring coordinated control of compressors, fans, pumps, valves, alarms and auxiliary devices. Although this order number has been discontinued, it remains commercially relevant for maintenance and replacement of installed MCX15B systems.

Technical Specifications

Compatible System and Applications

The MCX15B can be found in refrigeration plants, chillers, heat pumps, packaged air-conditioning systems, industrial cooling equipment and custom OEM control panels. The controller normally operates with application software developed specifically for the original machine.

Matching the order number alone does not guarantee immediate operation. Software, parameter settings, communication address, I/O allocation and wiring configuration must be checked against the installed controller and machine documentation.

Maintenance and Replacement Notes

Danfoss 080G0042 has been discontinued. Official replacement possibilities include MCX15B2 and MCX20B2 configurations, but migration is not necessarily plug-and-play. Replacement may require application-program conversion, wiring verification, connector checks and recommissioning.

Before purchasing a replacement, confirm the complete order number, type designation, nameplate, supply voltage, firmware, application software, communication interface and connector configuration. Back up the existing program and parameters whenever possible.

Related Models

Related models include MCX15B2, MCX20B, MCX20B2, MCX152V and MCX061V. Danfoss replacement order numbers associated with this legacy family include 080G0327, 080G0328, 080G0329, 080G0330, 080G0331 and 080G0332. The correct replacement must be selected according to the original hardware and software configuration.

Inquiry and Supply Notes

Please provide a clear photograph of the original controller nameplate and describe the installed equipment when requesting a quotation. Availability, condition, hardware revision, software status, connector kit and delivery time should be confirmed before ordering.
