Information About 2P273854-7
The 2P273854-7 is a Daikin main printed circuit board used in selected inverter-driven split-system outdoor units. Its electronic assembly incorporates compressor connections, sensor interfaces, protective circuitry, and dedicated connectors for controlling refrigeration system components. The board is identified in Daikin service documentation for compatible outdoor units, including selected RXS50K2V1B, RXG50K3V1B, and ARXS50G3V1B configurations. Its control architecture includes thermistor monitoring, an onboard service indicator, a protective fuse, and configuration jumpers for equipment-specific operating functions.
Key Features:
-
Main Inverter Control Board: Coordinates electronic control functions in compatible Daikin outdoor HVAC units.
-
Compressor Interface: Includes U, V, and W terminals for connection to the inverter-driven compressor.
-
Electronic Expansion Valve Control: Features an S20 connector for regulating refrigerant flow through the expansion valve.
-
Outdoor Fan Interface: Provides an S70 connection for the outdoor fan motor.
-
Temperature Sensor Monitoring: Uses an S90 connector for outdoor-air, heat exchanger, and discharge-pipe thermistors.
-
Reversing Valve Control: Includes an S80 connector for the four-way valve coil in compatible heat pump systems.
-
Overload Protection Interface: Features an S40 connection for the compressor overload protector.
-
Magnetic Relay Connection: Includes an S50 connector for the designated magnetic relay circuit.
-
Integrated Circuit Protection: Incorporates an FU2 fuse rated at 3.15 A, 250 V.
-
Diagnostic Status Indicator: Features a green LED A for service monitoring.
-
Surge Protection Component: Includes a V1 varistor for transient voltage protection.
-
Configuration Jumpers: Provides J6 for facility settings and J8 for defrost-performance adjustments in applicable equipment.
The 2P273854-7 delivers the reliability and precision required for inverter compressor management, refrigerant flow control, temperature monitoring, and coordinated operation of compatible Daikin HVAC systems.
