Alarms & Indication
Board mounted relays are essential components in building automation and HVAC systems. These board mounted relays help manage electrical loads using switches and controls. Our BAS and HVAC relays have a compact design and are mounted directly onto circuit boards. Similar to all relays, board mounted relays use low currents and voltages to control high-power circuits by opening or closing contacts in response to an input. Board mounted relays are a type of switching relay designed with efficiency in mind. These circuit board relays provide electrical isolation between circuits and high-power electrical systems. Using low-power control signals, they are used for switching motors, thermostats, dampers,lighting controls, and alarm systems. See our board mounted relays from Air Products to keep your BAS & HVAC systems operating smoothly and safely. We also offer an expansive selection of contactors, enclosed relays, general purpose relays, solid state relays, power relays, and lighting controllers suitable for various electrical applications.
