Bard 8201-159BX DPDT Pilot Duty Relay for HVAC Systems

The Bard 8201-159BX is a genuine OEM Double-Pole, Double-Throw (DPDT) pilot duty relay designed for use in Bard HVAC equipment. Pilot duty relays are specifically engineered to switch control circuit loads—such as coils, solenoids, and other inductive loads—safely and reliably within heating, ventilation, and air conditioning systems.

Key Features:

• DPDT Configuration: Double-Pole, Double-Throw contact arrangement provides two independent sets of switching contacts, allowing control of two separate circuits simultaneously
• Pilot Duty Rated: Designed to switch inductive control circuit loads including solenoid coils and contactor coils without contact degradation
• Genuine OEM Part: Direct factory replacement relay built to Bard specifications, ensuring proper fit and electrical compatibility with original equipment wiring
• Commercial-Grade Construction: Built for the demanding operating conditions found in commercial and institutional HVAC applications
• Broad Application: Commonly used in Bard wall-mount units installed in schools, healthcare facilities, modular buildings, and light commercial environments

The BX suffix is used by Bard internally to manage superseded or updated part revisions. This relay replaces the base part number 8201-159. Always verify terminal style and electrical ratings against your unit's wiring diagram or Bard service documentation prior to installation to ensure correct application.
