Product Description:
The 084B8020 is a drive for electronic expansion valves. Danfoss designed it for accurate control of superheat and temperature. The product is part of the Danfoss MCX Programmable Controllers family. The protection level is IP20 for safe operation.
The Danfoss 084B8020 ensures effective refrigeration control. It has one pressure transmitter and one temperature sensor. The mounting type is DIN rail, with a module size of four DIN modules. The dimensions are tiny, with a height of 110 mm, width of 72 mm, and depth of 54 mm. The gadget accepts current signal inputs of 4-20 mA and 0-20 mA. It also receives voltage signals ranging from 0 to 10 volts and 1 to 5 volts. A single digital input is accessible for additional control requirements. The output comprises one alarm relay rated AC-1 at 4 A and AC-15 at 3 A. When coupled to an external controller signal, the unit can serve as a valve driver. A battery backup of 18-24 Vdc enables a safe shutdown during a power outage. The net weight is 0.53 kg, making installation straightforward. The power source is 24 Vac/dc ±15% at 50/60 Hz. Power usage is only 10 VA, which ensures energy efficiency. IP20 protection rating applies to controlled areas. For MCX system integration the communication is enabled via CANbus. A Modbus RS485 serial interface is provided for more networking options. The unit has been approved by CE, EAC, Intertek Semco, C UR US, C-TICK, and LLC CDC TYSK.
The 084B8020 provides excellent application reliability. It is intended for use with a single evaporator and is compatible with AKV electronic expansion valves. The controller can handle both PTC 1000 and Pt1000 sensors. The valve output is suitable for AKV EEV valves. It is employed in refrigeration control, where precise regulation is required. The robust design with safety approvals ensures dependable integration.
