Product Overview

The YORK 031-02893-001 is a fully populated Motor Monitoring Board designed as an integral component of Johnson Controls YORK OptiView™ control systems for centrifugal chillers. This specialized control board serves as the critical interface between motor-mounted sensors and the chiller’s microboard, performing continuous real-time monitoring of motor health parameters including winding temperatures, bearing temperatures, vibration levels, and cooling coil leak status . The 031-02893-001 is specifically engineered for YORK YK series centrifugal chillers, which incorporate single-stage compressor designs renowned for their reliability in mission-critical applications such as hospitals, chemical plants, and gas processing facilities .

The YORK 031-02893-001 distinguishes itself from its counterpart, the 031-02893-000 board, through its fully populated component configuration. The -001 variant includes populated RTD analog input and vibration analog input components, making it capable of supporting all sensor types required for comprehensive motor monitoring, whereas the -000 board lacks these components and is restricted to applications not requiring those sensor inputs . The 031-02893-001 board receives +24VDC, +12VDC, and -12VDC power at terminal block TB4 and features onboard voltage regulation to generate +5VDC and +15VDC supply voltages . As an OEM replacement part for YORK HVAC equipment, the YORK 031-02893-001 ensures seamless integration with existing OptiView™ control centers and maintains the high standards of reliability expected in critical cooling applications .
