DANFOSS 084B8080 084B8080007306CC164 Product Description

Overview

DANFOSS 084B8080 084B8080007306CC164 is a Danfoss Optyma Plus condensing unit controller, with base controller code 084B8080 and extended assembly or serial reference 084B8080007306CC164. The Optyma Plus controller is an electronic control unit for Danfoss refrigeration condensing units, managing compressor, fan, expansion device, pressure and temperature signals and providing local control together with Modbus communication. The extended suffix is treated as a configuration, revision or serial identifier for the controller assembly; the exact suffix meaning should be verified against the controller label, condensing unit documentation or Danfoss order record. The unit is used as a replacement controller spare in existing Optyma Plus refrigeration installations.

Features

DANFOSS Optyma Plus controller 084B8080 operates from a 230 V AC supply. The controller provides 7 analog inputs, 2 analog outputs, 3 digital inputs and 5 digital outputs. It also includes one TRIAC output. Communication is Modbus over RS485, allowing the condensing unit controller to connect to a refrigeration supervisory system, building management controller or other Modbus network for monitoring, parameter access and control integration.

The controller is designed for condensing unit control in refrigeration applications. Its analog inputs typically connect temperature, pressure or other refrigeration sensors; digital inputs and outputs interface compressor, fan, valve, alarm or auxiliary circuits; analog and TRIAC outputs support control of fans, valves or modulation devices according to the Optyma Plus programming configuration. Gross weight is listed as 632 g. Public Danfoss store records identify the product as an Optyma Plus controller for compressor and condenser control, with Modbus RS485 communication and the listed input and output count.

Principle

The Optyma Plus controller receives refrigeration process signals through its analog and digital inputs. Temperature sensors, pressure switches or transducers, demand signals and auxiliary status inputs provide the controller with condensing unit operating conditions. The controller evaluates these signals according to the configured refrigeration program and Modbus parameters, then switches or modulates compressor, fan, expansion device, alarm or auxiliary circuits through its digital, analog and TRIAC outputs.

The RS485 Modbus interface exchanges operating status, sensor values, setpoints, alarms and parameter data with an external supervisory system. Controller replacement should match the original supply voltage, I/O configuration, software version, Modbus address, sensor wiring and condensing unit model. Because refrigeration controllers may carry refrigerant, compressor, fan and safety-related control functions, configuration backup, sensor calibration and wiring verification should be completed before the replacement controller is placed into service.

Applications

DANFOSS 084B8080 Optyma Plus controller is used in refrigeration condensing units, walk-in cooler and freezer systems, cold storage, refrigerated display cases, food and beverage refrigeration, process cooling, commercial refrigeration, chillers, condenser fan control, compressor protection, plant-room refrigeration control and building management integrated refrigeration monitoring. It supports local condensing unit control and Modbus-based supervision of refrigeration equipment. In existing Optyma Plus condensing units, the controller serves as a direct replacement electronic control spare when the original controller version, software and wiring configuration are verified.
