Description
The Weil McLain 510312166 Transformer-Relay with Bale Wire Combination is a step-down regulator integrated with a relay assembly used to supply low-voltage power and control switching operations in boiler systems. It converts 120V input to a stable 24V output while enabling coordinated relay operation for system startup and safety interlocks. In HVAC systems, it is used in gas-fired boilers and hydronic heating units where both control power and relay switching are required. The unit is mounted in the steady voltage supply, a reliable circuit for switching operation of the burner and ignition-related components.
