Bard HVAC 8201-079BX Solid State Lockout Relay 24V

The Bard HVAC 8201-079BX Solid State Lockout Relay 24V is an electronic control unit that interrupts system operation when abnormal conditions are detected. It monitors safety inputs from ignition and limit circuits during operation. The relay uses solid-state circuitry to process signals without mechanical movement, allowing fast response to fault conditions. Added in the control section, it stops system activity when unsafe sequences occur and requires a reset condition before restoring normal start-up control. Utilizing low-voltage logic ensures immediate response during fault conditions, and proper wiring remains essential for achieving optimal output.
