The Functional Devices TR75VA004 is a versatile 75VA multi-tap transformer designed for reliable power stepping in commercial and industrial HVACR control circuits

The high-grade construction resists the common pitting and corrosion found in aggressive boiler water environments

it utilizes a highly sensitive bimetal element and a factory-calibrated stainless steel ball-in-seat to provide linear branch pressure response across a 55 to 85°F setpoint range

MAMAC Systems EP-321 Tristate Pneumatic Transducer 30067439-890 verify static pressure and temperatureThe MAMAC Systems EP 321 is a high performance tri state to pneumatic transducer designed for precise HVAC pneumatic control. This unit effectively bridges the gap between digital controllers and pneumatic actuators by converting a 24VAC VDC tristate signal into a stepped pressure output. Engineered for reliability in building automation systems, the EP 321 features a 0 20 PSIG output range and a sophisticated pulse train mechanism that allows any
