Product Description:

Type code 084B4164 mainly represents a Danfoss MCX series controller with a mounting type DIN Rail that allows direct installation in standard control racks and reduces cabinet assembly time. Its power supply 230V AC aligns with common mains supplies and removes the need for auxiliary transformers in many installations. Communication protocol Modbus with optional LON provides multiple field-bus choices and enables integration with building management networks.

The compressor relay rated 16 A supports direct switching of single compressors and sets the design limit for contact selection. The module’s defrost relay rated 10 A controls heater or valve defrost circuits and defines safe switching limits for defrost equipment. Also, the evaporator fan relay rated 10 A handles fan motor loads and provides a clear limit for motor starter requirements. Further, its auxiliary relay “1” rated 4 A offers a low current output for signaling or light loads. This device uses three analog inputs which accept multiple sensors and permit flexible temperature or pressure monitoring. Digital inputs of maximum “2” accept binary signals for door switches or external alarms and simplify interlocks. Expansion valve type TXV matches thermostatic expansion valve control and preserves valve compatibility for refrigerant metering.

The model 084B4164 opens with input signal PTC 1000, providing a defined temperature sensor interface and supports accurate temperature measurement. The controller’s power consumption 2.3 VA limits heat dissipation in small cabinets and simplifies auxiliary supply sizing. Number of compressors with max “1” defines the supported compressor count and guides system sizing for single-compressor evaporators. Its valve output type EVR indicates direct drive for solenoid valves and ensures correct actuator matching. Finally, the number of evaporators up to “one” maximum sets the evaporator control scope and clarifies deployment in single-evaporator systems.
