York 331-02550-101 Board Kit

The York 331-02550-101 Board Kit is a comprehensive I/O management solution engineered specifically for high-capacity air-cooled liquid chillers utilizing hermetic scroll technology. As a critical HVAC control board kit, it serves as the central processing interface, regulating digital signal inputs and outputs in parallel to the system computer. This kit is a factory-direct replacement designed to maintain operational stability in York chiller applications, including YCAL models ranging from 12 to over 90 tons. By integrating the 031-02630-001 I/O board alongside specialized flash memory cards—such as the 031-02755-001 or 031-02755-003—this assembly ensures precise temperature regulation and fan speed modulation. Built for the rigors of industrial environments, the robust circuitry provides protection against electrical noise and thermal stress. This original equipment manufacturer (OEM) component is essential for technicians tasked with restoring complex chiller communication logic and optimizing liquid chiller efficiency without compromising system integrity.

• Precise Signal Processing: Facilitates seamless parallel communication between the central processor and field devices for accurate system diagnostics.
• Enhanced System Stability: Regulates critical functions, including multi-stage compressor cycling and fan performance, to prevent operational drifting.
• OEM Compatibility: Designed specifically for York hermetic scroll chillers, ensuring direct fitment and native firmware support via included flash cards.
• Industrial-Grade Latency Control: The integrated microprocessor delivers real-time data acquisition, allowing the system to react instantly to dynamic load changes.

What chillers are compatible with the York 331-02550-101?
This kit is primarily designed for York air-cooled liquid chillers using hermetic scroll compressors and handles tonnage variations through specific flash card configurations included in the box.

Does this kit replace the obsolete 031-02630-001 board?
Yes, the 331-02550-101 is the designated factory replacement for the older 031-02630-001 I/O board, offering updated logic and improved communication protocols.

How do I determine which flash card to use for my unit size?
The kit typically includes cards for different tonnages; the 031-02755-001 is usually calibrated for 12-86 ton units, while the 031-02755-003 is for units 90 tons and larger.
