Weil McLain 510-350-211 Solid State Electrical Delay Timer, 2.5 Min Delay On Make, 24V

Description

The Weil McLain 510-350-211 is an OEM solid state electrical delay timer engineered for precise sequencing in Weil McLain boiler control systems. Featuring a 2½-minute delay on make, this timer ensures controlled, staged startup of connected loads — protecting equipment from premature energization and reducing wear on downstream components.

Built on solid state technology, this timer eliminates the mechanical contacts found in traditional electromechanical timers, delivering greater reliability, longer service life, and consistent timing performance across a wide range of operating conditions. Designed to operate at 24 volts, it integrates seamlessly into standard low-voltage boiler control circuits.
