Gould A132D is a general purpose control relay used in electrical control systems. It features an electromagnetic coil that, when energized, actuates internal contacts to open or close a circuit, allowing a low‑power control signal to switch a higher‑power load. Relays like the A132D are commonly used for logic functions, interlocking, sequencing, and auxiliary control in industrial machinery and automation panels. The device provides electrical isolation between the control input and the switched output for safer and more reliable operation. These relays are typically found in motor control centers, control cabinets, and other applications requiring reliable control switching.
